  1. Hi @Enigma I can't help, but could you make your request a little clearer? A&E in the UK is Accident and Emergency, so it looks as if you are trying to go to hospital... (-: Best Regards, Adrian
  2. Hi @Ron @Enigma Since it's a detachable part, some early twin tubes do have the later tommy bars. Also, as the welded style ran out, there may be some mixing of new and old style. Below is R1228. With some variations in the welding quality, these are seen up to at least R6386, although the Standard type is fitted to R5381 and R6342, so these are either replacements, or the start of the Standard type filtering in. With Ron's frame being well before these at R3402, it seems likely that it was a welded bar. Incidentally, my Twin Tube is R6599, which has the Standard tommy bar. Best Regards, Adrian
  3. Edited to add that we were typing at the same time (-: ) Hi Ron, The forks come in two types, identified as Peaked and Flat for ease. If you look at the shoulders of the fork on your Twin Tube (below), you can see that the top surface of the is peaked, and on the socket, where the legs slot into it, the side has a wide upside-down V (useful for identifying in photos). For your bike R49799 (below) it has the other type of shouders, which are flat on the top surface, and the socket where the legs slot in is straight across. The forks are interchangable. So far as I can tell from observation, all of the Twin Tube, and the start of Single Tube production had the Peaked type. Around R13244 (a single tube), the first Flat ones are seen, to around R22763. After this, there seems to be a random mix of Peaked and Flat to about R31935, after which the forks are Flat again to the end of production. For the pedal boss, there's (at least!) two types. Initially, the pedal arm were used as off the shelf, and I'm told (but can't verify) that these were even threaded for standard pedals. All of the Twin Tube, and start of Single Tube production have these plain arms. The pedal boss occurred around R21622, with an extra piece being welded onto the arm for support. The piece resembles a metal doughnut, with chamfered edges on both external circumferences, presumably so it could be assembled either way, and have good weld penetration. This first type of boss must have been quite work intensive to produce, and a second type appears somewhere before R31935, which is conic, and integrally cast on the arm. This continues to the end of production. So your pedals are WW2, but late pattern. R4154 (below) has the Welded tommy bar, and these continued through to at least R6386, so I suspect yours was originally, but the one fitted looks original, just later. It is evident on the drawing of a Twin Tube below, but I don't know the origin or date of the drawing. Best Regards, Adrian
  4. Hi, @Oh Five I was at 637VGS at Little Rissington as a staff cadet for several years. My first flights there must have been around 1981 with Kirby Cadets, as you describe. Additionally we used a 4 wheeled trailer signal caravan with Aldis lamp for airfield control. Later we converted to Venture T2 SLG. By that stage we had two yellow lightweights, one with a foam extiguisher mounted in the rear, the other GS, sometimes used to haul 140litres of jerricans of 2 star petrol for the gliders from the local petrol station, amongst many other tasks. I seem to recall these were 75AM56 and 75AM58. The Kirby Cadet trailer survived into another role with a cage welded to it, full of 'No Entry, Flying in Progress' signs which need to be put out and recovered around the airfield every flying day. Best Regards, Adrian
  5. Hi @Ron Very nice (-: Always good to see another turn up. I currently have 44 twin tubes listed by frame number (and have seen a couple of others that I was uable to get a number for). My total list by serial number is now 326. The transfers on the head tube (Broad Arrow, patent number) are the same as for later bikes. The piled rifles transfer isn't used on these. R3402 is the Twin Tube pattern frame. The closest survivors I have listed are R2953 (in East Sussex) and R3493 (in BC, Canada). The closest survivor I have a decent picture of is R3641 from Questmasters, here (scroll down the page): https://www.questmasters.us/Bicycles.html Originally yours would have had a black enamel undercoat with the early war British Green paint. The cast brackets for the wingnuts had only been introduced a short while before, to replace the early ones made from angle iron. Is the tommy bar for the handle bar release welded onto the top of the nut, or does it pass through a hole in the nut? It was probably still being welded at this point. The pedal arm on the photo appears to have a boss on the pedal hole to help support the pedal? This feature wasn't introduced until well into single tube production, so it is probably a replacement. It has the correct 'peaked' front fork. I hope this helps. Best Regards, Adrian
  6. Hello, All, How do you value a jeep? Mine is the one pictured above. As mentioned, it is complete, a bit of a Heinz 57, but mainly WW2. Ex British army. Not driven for 11 years now, but in dry storage. Thanks for any thoughts. Best Regards, Adrian
  7. Hi @IamaFerret From my own experiences with this problem: Starter foot switch burned, damaged, poorly earthed. Earthing and good contact in general needs to be perfect. Run earth direct to starter motor. Or something else (-: Best Regards, Adrian
  8. Hi All, Picture from Google Earth. Reims Place Royale. I couldn't get exactly the same angle of buildings relative to the statue, so I think the statue has been moved further into the centre of the square. Best Regards, Adrian
  9. Hi @Morris C8 I'm not great with uniforms from this period, but I think the two guys in the middle are wearing French 1915 pattern sidehats. Best Regards, Adrian
  10. Hi Wally, It's taken me 20 years to answer a question for you (-: (you answered some questions for me once). Yes, it's a pun, sometimes seen on trucks today. One side is marked 'Passing Side', the other 'Suicide'. (-: Thanks for your past help. Best Regards, Adrian
  11. Hi @mikej.1981 and welcome. @seawolf was last seen Feb 12th 2020, so not impossible. As a help, if you put @ and start to type the persons identity, a drop list comes up. Pick them up off that, and a message will be sent to their last email automatically. Best Regards, Adrian
  12. No Problem @Listerj123 It's probably the entier light unit. The info came from here, second post down: https://www.key.aero/forum/historic-aviation/140142-more-treasures-from-the-garage?page=6 Photo credit: 'Air Ministry'. Good luck with the restoration. (-: Best Regards, Adrian
  13. Hi @Listerj123 4F is an RAF code which is apparently for equipment associated with Air Compressors and Servicing Trolleys. Best Regards, Adrian
  14. Hi, @MartinN I agree with @Richard Farrant I just measured a parabike wheel without the tyre, and it is close to 24" diameter x 1" 1/8 width. So the 26" x 1" 3/8 should fit fine, and was a standard WW2 size. Best Regards, Adrian
