Recommended Posts

OK what is it and does anybody want to save it ? found in a scrap yard today. AM Air Ministry Compressor Trailer fitted with an electric motor rather than the original petrol engine.

Low pressure pneumatic servicing trolley possibly Mk 1b, A few fitted with elec motor for use in hangars driving pneu tools spray guns etc Most were twin cyl petrol ; we got rid of our last one at RAF Leuchars in 1993- it was still in daily use and reliable better then the rubbish that replaced it !!

Done some research & found that this one is pre-war (about 1936) and converted from a petrol engine to electric motor quite early on in its life, correct me if I'm wrong please.

Saved another one yesterday at a very reasonable price, its basically the same but a later build I think, heavy duty 3 stud wheels instead of the flimsy 4 stud wheels.

Almost the same compressor pump but I think its been converted to a 2 cylinder petrol engine later in its life ?

Chassis & hitch are the same as the early one so perhaps there was a major refit of these & that extended their life into the 1980s as ted & Richard pointed out,

Into storage for the time being but long term plan is to make 1 out of the 2 using as many early parts as possible including the AM data plates.

A nice bit of RAF airfield kit to go with my WW2 RAF vehicles,

OK any volunteer's for starting the engine when the time comes ? only qualification is brave or stupid & lots of life insurance :nut:

If it can do this to the cranking handle imagine what it can do you your wrists :nono:

Ian, you must tell us the name and address of your 'local' scrap yard as you seem to find some interesting loot and far more interesting than my nearest scrappy that is 100% non-military.

 

BTW - Who is to say the starting handle broke when being used for its intended purpose; someone could have told the Corporal where he could stick it and it broke in the ensuing struggle while trying!

Afraid not Ian; The problem is since leaving service all manner of things will have been done by owners to try and keep them running. However what I must say is : They were "normally" easy to start BUT if the handle shout leap off its obviously much heavier than most !! ouch- make sure the pawl/peg that allows the handle to disengage is functioning correctly and that all guards are securely in place- there are many places that are ready to snatch hands clothing etc on them- don't mean to teach anyone to suck eggs but ----- . I think an e mail to Hendon might produce the ground equipment data book leaflets for you. There is a picture of one in Adkins book on page158 it is shown with the 3 stud hub/rim arrangement. They were prone to carbs overflowing whilst running- yes the mag is directly below the carb; We had one on fire in the GSE workshop- a 1917 Belfast truss hanger - just before we got rid of the last one. We were lucky a couple of lads got stuck straight into it with BCF extinquishers.

finally a blue was introduced for Ground Equipment in the 1950s It was BSC 169 Traffic Blue - unfortunately it was removed from the BS 381c in about 1980, the yellow was BSC 356 golden yellow and the IRR matt green was BSC 285. I have found some RAF documents which allowed certain tactical units to paint ground equipment in BSC 241 matt dark green prior to 285 being universally introduced. Sorry I can't be of more help and good luck.

Ian I've got similar sheets for Mk 1 & Mk 1A, plus some earlier types. Do you have a particular one in mind?

Hi Clive I would be very gratefull for sight of the previous Marks; When I left the Service in 2004 no way did I ever imagine I would be corresponding on the subject of RAF ground equipment that against the enemies of age, no spares and user- abuse we managed to nurse along so as to be availible to the end user.

Hi Clive the top photo (mk1) is the same as the blue one in post #6 & the bottom photo is the same as the (mk 1A/B) in post #4 so we are still looking for the very early trolley (AM) as in post #1

Ian I have looked through the 81 trolleys in Section 4F but the only ones that bear any resemblance to #1 are the three I have posted up. Bear in mind this listing is circa 1960 & may post-date the use of #1.
