G121 ?

[Motorpool-Mac]

I just bought a huge lot of parts from an old guy who got them surplus from the Air Force Base here years ago. A lot of NOS parts – I keep running across this part numbers on the boxes that start with G121. Anyone have any idea what vehicle G121 would be?

Thanks
Daniel

If it is in front of a part number, it would be the vendor's number. Wayne

So a vendor would be like the parts supplier?

And in that case, a stock number like: “G502-01-96319” would not necessarily mean that it was a generator repair kit for the G502 Dodge? I was assuming that that G number was the vehicle number because a few parts with that G502 prefix were also marked “SNL-G502, G503, G507” I assume referring to the pats listing for those vehicles.

Does SNL stand for “Stock Number List” ? And does it refer to a parts listing like the ORD9?

Thanks so much!

I don't know about WWII parts, but if it helps a G121 is a 3/4-ton 4x4 Dodge WC-55 Fargo truck. Wayne

The WC-55, was a Dodge 3/4 ton truck with winch (WC52), but some one came up with the idea to arm them with a 37 mm cannon. So, they mounted a 37 mm cannon in the bed. It was great for training, but in combat, it was a complete failure. Thin sheet metal of a truck is no match for a Panzer MarkIV. The 37 mm cannon was nothing but a "wake up the crew device". It could not stop the tanks that were being made in 1942. The cannons were removed from the WC55s, that made them back into WC52s.
Two more notes on the WC55 while I am boring you to death, It is one of two Dodges that were used by the Marines in WWII, the other truck being the WC53 Carry All. The WC55, was called a WC55, the G121, and it had it's own M number also it was called the M6 gun motor carrage, alot of names for a truck that was very short lived.

Truck

It was just a idea that was ahead of its time. It would be great today to get rid of tailgaters. Wayne

RE: Truck

Hey Mac, post photos of the parts and maybe someone will be able to ID them.

Wow! Thanks!

Most of these parts are still unopened in wax wraps – I’ll try and get some photos up this week. I actually have a lot of parts that need identification, and a lot of them I will need to sell as well.

If indeed the M6 Gun Motor Carriage is what the G121 is referring to here, then the parts marked G502 should be for the same vehicle; the ¾ ton Dodge weapons carrier (and vice versa). And I have a lot more parts marked G502 and G507 (which I believe is the Dodge 1 ½ ton 6x6.)

One thing that threw me was that the Generator Bushing sets are marked GPW-18274. I understand the GPW to be the Ford built jeep. I have two other parts with a similar GPW number and neither have a G121 number. The one has G067-0900810, and all three have a number starting with WO_A.

According to this webpage: http://www.milweb.net/features/gnumbers.php the G67 is the White Motor Co. Scout Car, and David Doyle’s Standard Catalog of US Military Vehicles confirms it as G067.

The prefix was coded to the first vehicle that it was used on - a lot of the M-series electrical parts start G740 for example.
