This is turning into an interesting query! As a result of this I have been looking at my CMP listings.
CHEVROLET:
Z 5194641 to Z 5195730 Contract SM 2485
[1942] "TRUCK 15 CWT. 4 X 2 AA (20 M.M.)" C.15 E.g. Z 5194984!!
L 4999725 to L 4999726 Contract SM 2572 was originally for "LORRY 3 TON 4 X 4 DERRICK ARTICIZED"LORRY 3 TON 4 X 4 B/DOWN GAR WOOD CA5P OR HOLMES W45CBE OR CE
CRANES; BRKD-3 ARTICIZED] as per IWM photo KID 2928 BUT
IWM photo KID 3072 shows L 4999725 as being to Contract SM 6065...WERE THESE REBUILT UNDER SM 6065 TO LIGHT AA?
SM 6065:
H 5582513 to H 5582612 Contract SM 6065 "TRACTOR 4 X 4 LIGHT AA"
H 4999629 to H 4999724 Contract SM 2573 "TRACTOR 4 X 4 LT. AA ARTICIZED" C.30 or "C.30- 444-M LAAT 2" E.g. Serial # 2844122313 built 20 August 1942..E.G. H 4999629 IWM PHOTO KID 1416
FORD:
Z 5195731 TO Z 5196440; Z 5348761 to Z 5348960 Contract SM 2485 "Truck 15 cwt 4 x 2 (AA 20 mm) A.A. NO.1 MK. III" Model C101WF or F.15
E.g. Z 5193619 IWM PHOTO KID 3380; Z 5195764 IWM KID 2273 E.g. Z 5196119 Serial # 110574 built 18 January 1943 and Z 5195771 Serial # 113211 built 27 January 1943 were originally F-15421-M-VAN-6 with Van-6 body and were part of 2,000 C.15 and F.15 trucks converted by Dennis Motors Limited, Guildford, Surrey to 20-m.m. A.A. Gun platform with Vauxhall Motors Limited manufactured gun carriage-cum-mount. NOTE THAT THIS F.15 HAS BEEN PHOTOGRAPHED WITH THE GUN REMOVED; SEE GEOFF'S POSTING BELOW [15 April]
H 5327001 to H 5327600; H 5589105 to H 5589404 Contract SM2487 "Tractor 4x4 Lt AA" Model C29QF F30 A/A VARIANT e.g. IWM PHOTO KID 1968 C29Q
F30
H 6100201 to 6100448 Comtract SM 6111 "Tractor 4x4 Light AA" E.g. H6100380
assembled by Pearson’s, Liverpool 1944 Model C29Q? F60S
H 6100505 to 6101404 Contract SM 6143 "Tractor 4x4 Light AA" F60S
Z 6167447 Contract SM 5186 "Truck 15 cwt 4x4 AA 20 mm" C291WQ F.15A
H 6243634 to H 6244553 Contract SM 6143 "Tractor 4x4 Light AA" Model C29QF F.30?
However, I also found something interesting:
L 6153025 to L 6155024 Contract S 8189 "Lorry 3 ton 4x4 GS (Air Portable)" W0T6..this was the only officially Air Portable truck in the Chevrolet and Ford listings. There is no evidence YET that I have found that any of these CMPs were rebuilt in the Airportable role. Therefore may I make a suggestion that any AP Bofors guns were towed by Jeeps, Morris-Commercial Tractors [although only {6-pounder?] and 17-pounder A/T guns are known to have been towed, and possibly the AP Carriers. Could the W0T6 Air Portable version have been used inthe tractor role?
I am intrigued by that one-off F.15A...I wondered whether that was a prototype Airportable truck?[
