Following another topic in this forum discussing the filter that may fit this canister, I found something that I would like clarification on. I have a 1954 M170 with what i believe is the standard military Jr. canister.

My 1953 M38A1's housing lid is stamped, on the conical part of the lid, "Replace element with MS35346-1". No other markings or stampings on the lid or body. The body does not have a separate drain hole at the bottom for draining the filter. _________________ 1951 M38

Hi Gary,
I have been researching this topic and have found that the military Fram and Purolator had many changes over the years.
Their are a ton of great pictures all over the internet of these differences so I really don't want to start stealing them and posting them here.
From what I can gather:
Fram only has: "Military Standard Filter" on the cover.
Purolator has the same but also has their name Purolator on it and assembly number.
The Fram bottom filter housing has what some people describe them as dimples.
Purolator does not have this.
Their are differences in drains also in years.
I have seen some covers say: "Military Standard Filter" or "Military Standard Junior Filter"
The problem I have run into is people just assume they have a military standard filter housing because it is on their engine.
Could your blank cover be another Military standard version? Possibly!
Honestly I think someone could write a book just on this subject.
The problem I see with my M38 is if you want to be 100% factory it should have the cuno filter. Yes the military standard filter housing were added later on but they probobly installed whatever left over WWII stock first and then new stock. That is only my thought and not a fact.
In my M38 parts book it does list Fram 540501 assembly. The cover is ordnance part number 7529093. So if anything I guess this is what you would want to shoot for if you wanted this type of filter instead of the cuno.
Confused yet? me too... =O) _________________ Matt, Truck 1/4 Ton 4x4, M-38 (G-740)

The serial number split in the M38 ORD9 is a typo. That serial number split actually took place in the M38A1 production. The only M38's to come from Willys with the military junior were the 6 pilot models in the spring of 1950. All production M38's from Sep 1950 thru 1952 came with the Cuno. _________________ Wes K
