Engine number

Hello, my name is Václav and I am from the Czech Republic. I bought a Jeep M38 and I have a few questions. Thank you in advance for your answers. The engine block has the correct number for M38-804380, but the upper number behind the water pump is not marked MC before the number, there is only number-795888. Are there engines for the M38 that did not have the letter MC in front of the number? The number on the label behind the front passenger seat is 25359. According to information, this Jeep was imported to the Czech Republic by an emigrant from Canada when he returned to his homeland. I would like to add photos, but I don't see it in the menu. Excuse my text from Google Translate. Thank you.

Both the L134 & the F134 engines have a serious problem maintaining their serial numbers because when the block upper surface is decked (shaved) the numbers are usually obliterated. Often, when this happened the machine shop would restamp all or part of the serial number back above the water pump. Also Willys often had a tendency to use a lighter stamping of the prefixes. All M38's left Willys factory with an MCXXXXX serial there. Willys also produced spare engines in separate lots under US contracts and these spare engines had a RMCXXXXX serial. The serial on the tag behind the passenger seat indicates your M38 is a late June or early July 1951 M38. Do you have a dash serial plate?

Oba motory L134 a F134 mají vážný problém se zachováním svých sériových čísel, protože když je horní povrch bloku vyhozen (oholen), čísla jsou obvykle vymazána. Často, když se to stalo, by dílna stroje přemístila celé nebo část sériového čísla zpět nad vodní čerpadlo. Také Willys měl často tendenci používat lehčí ražení předpon. Všechna továrna M38 odešla z Willys s řadou MCXXXXX. Willys také vyráběl náhradní motory v oddělených šaržích podle amerických smluv a tyto náhradní motory měly sériový RMCXXXXX. Sériové číslo na štítku za sedadlem spolujezdce naznačuje, že vaše M38 je koncem června nebo začátkem července 1951 M38. Máte pomlčku se sériovým štítkem?

Thank you for the answer. I have photos, but when writing a post it is not possible to put them directly to the post, they must be in the photo gallery?

Yes. Or any other photo web site where you have them in a public file and can provide a url for each photo.

In czech

Ano. Nebo jakýkoli jiný web s fotografiemi, kde je máte ve veřejném souboru a ke každé fotografii můžete poskytnout adresu URL.

Yes I understand, but my album is not in the members' albums on page 23, so I can't put photos in it :(

Photos of the numbers from the block and the engine are in my album, also the number on the label.

That stamping was not done by Willys. The block has had it's top deck machined and someone restamped the serial in the field leaving off the prefix.

The MC and the 25359 are original Willys stampings. The 38 and the two dots are not done by Willys.

Thank you for your time and advice, I have more questions, but I can't add photos to the album anymore, the upload takes a very long time and to no avail.

You must limit the file size of your photo to avoid the lengthy upload time and frequent failure to finish loading. Limit your photo file size to 4oo to 500 K or less.

Czech:
Musíte omezit velikost souboru s fotografií, abyste se vyhnuli dlouhému nahrávání a častému nedokončení načítání. Omezte velikost souboru s fotografií na 4oo až 500 K nebo méně.

Thank you for your patience with me, I have already reduced the photos and uploaded them.
How can the Canadian production of the M38 CDN from Ford be distinguished from the production of Willys?
