  1. The "A frame thingy" behind the take out engine on the right of the photo is actually part of the engine. It is the stays for the exhaust mufflers that sit in a frame bolted to the top of the diamond shaped engine mounting frame and held up at the back by those two stays. Later installations did away with the mufflers and just had plain pipes to the fishtails in the overhang of the upper hull. I note that the box for the new engine is marked as containing an engine with Scintilla mags rather than Bosch mags which didn't have a booster coil and so the engine wiring was slightly different, though easily changed to suit.

  2. The figures quoted above give a reasonable picture of general WW2 tank fuel consumptions but must be interpreted. Shermans, Grants and Valentines were built with both petrol and diesel engines. The diesel versions gave at least 50% better fuel consumption and were quicker. A tank has to work very much harder to move on soft or seriously broken ground or on gradients so its fuel consumption is very much higher in these conditions than on firm level ground. This will result in about four times the consumption that can be obtained on a road. Covenantor and Stuart will do rather better than the others because they are much lighter but all the others if they have petrol engines will average about 0.5 MPG in real life. Please remember that the official testing was not done in particularly scientific conditions and should be read with the statement of the conditions at the time of the test because that makes a big difference.

  3. Hi Louie, Crossley made many types of vehicle over many years. It would help if you could narrow the search down a bit by telling us what vehicle you have. Also it would help if you put your location in your personal details so that it is displayed under your user name so that people can see if you are local to them or not. This forum has people from all over the world which is a big place. In general people can't be bothered to search back through someones previous posts to see these details so adding them greatly increases the chance of people helping, which they will if they can but you need to make it easy for them if you can.

  4. Try www.sealsdirect.co.uk They offer a fair selection and have their catalogue on line. David
  5. It was quite common for them to be changed to twin rear wheels in civilian life. David
  6. John, I think that that is an excellent idea, it is certainly very hard to see that it could do any harm. The worst that could happen is that the oil oozes out and then you are no worse off than the standard arrangement. David
  7. I was shown a photo once of a low garden 'fence' made from overlapping carrier sprockets, quite a number of them. It was allegedly well know to all the carrier owners in the area and as the guy was not interested in selling his fence, it got a bit shorter from time to time. I wonder what would be a fair swap for that carrier track ? David
  8. Quite right ! Thanks Adrian David
  9. This is an M4 75mm Sherman fitted from new with vertical volute spring suspension and built post August 1943. It is what is known as an "ultimate series" tank as it has the bigger front hatches that don't intrude into the less sloped glassis plate, the final version of the radial engine installation with the oil filler cap in the rear section of engine deck, no cutout in the lower edge of the upper rear armour. Inside the wiring, seats and most stowage are very different to earlier Shermans. The turret is the correct "high bustle" late 75mm one with the correct vision cupola but the gun mantlet and turret front are from a much earlier Sherman. The mantlet should be the full width of the turret front which should have extra slots in it for the mounting bolts of the M34A1 mount. It is possible that it was originally a 105mm howitzer tank as these had basically the same turret but with a different front, gun and mantlet but only by looking at the internal ammunition stowage would one know.

  10. It's an Austin K3 but I don't know what 'ZC' means but it might relate to the original rear body, of which there were many types. There were 17,097 built between 1939 and mid 1945. Early ones had 34x7 tyres (later called 7.00-20) with twin rears. Later trucks were on 10.50-16 singles all round. Engine was a 60 hp six cylinder. There are very few left and in the UK that would be regarded as a good cab, ours have rusted very badly. Good luck with it. David
  11. I have one similar to the green one in the post above but of considerable age, painted red oxide and measuring 7 1/4" extreme length (which is rather shorter than the green one I think). It does not have the rubber nozzle. I have always assumed it was ex-mod as it came from a surplus dealer but there are no markings on it. It has a vent pipe that comes out of the base of the tube part and curves over the part that seals to the can. If the green one above had one it would be just visible at the very top of the photo. David PS, I have had mine for about 30 years and it was far from new when I got it.
  12. Oh that is depressing 😫. At least you have a better crank. David
  13. I think that all your points are good and that it is very acceptable to restore any vehicle to as close as possible to how it was at some point in its history. The problem comes when making it into something that it never was, or even more so if making it into something that it could never have been because a key 'improvement' (to use a silly example - air bag suspension) had not been developed then. To restore a Sherman to exactly how it came out of the factory is very difficult now, regardless of your budget, because some parts are simply not available and re-manufacturing them not really practical, so a degree of compromise is almost inevitable. Wherever you draw the line will draw criticism, mostly from people who don't restore things themselves. David
  14. Yes, Centurion. And very heavy ! David
