M-38A1 QUIZ-HOW WELL DO YOU KNOW THE M-38A1?

Post by Joe Gopan » Sun Jun 13, 2010 12:10 pm

When I built my M-38A1 out of NOS parts back in 1975, one major component I instalLed was a NOS Crated M-38 Rear Axle Assy.
I changed the obvious, the Brake Backing Plates with Shoes. It appears 100% M38A1 now, but there is one minor obvious and very visible detail that is still M-38 that could not be changed.
Can anyone guess this detail that will identify the Rear Axle Assy as M-38?
I'll bet some of the M-38 Judges will not be able to tell. :wink:

Good try, :) but not quite, the holes are there and will have grease fittings on Crated Axles before the date of the urgent MWO G1W43 12 Jan 54 to replace them with plugs because of the chance of over lubricating. Both the M-38 and M-38a1 have the same axle housing.

Good try, it is 2430 O.D. out of the crate. Not the answer tho. Looks like the field of M-38/M-38A1 experts has narrowed. I gotta do some more of these, this could be fun. :wink:

Another good try, but it is possible for the dates to overlap. Not the answer tho.

So what was the answer?
I am seeking information on M38A1's configured for MP use from 1953-?.

I am also interested in equipment and uniforms worn and carried by MP's during this timeframe.

Do the Relief valve differ on the rear axle cover?

actually, Does the M38 cover have baffling on the inside as opposed to the 38A1 ? :roll:

Most likely not if the axle assy is dated earlier than November 1952. And it is possible that the Depots would to the Mod before shipping an axle assy or order it done at the destination. Yjere was a 5 Nov 52 MWOconcerning adding the baffle thru a mod or installing a later cover.The MWO was not urgent and may have taken months, years or never. I have one more NOS M-38 Rear Axle Asst that I removed from the crate. We bought them at Firestone Motors in 58.
