After reading D. O'Connor's two postings, he appears to have (and be
leaving others with) the impression that GPWs and MBs were assembled from
strictly random components and that this resulted in very few Jeeps whose
numbers originally matched. This has NOT been my experience, and I'm
wondering if it has been that of others. I have always understood (and
seen) that the engine, frame and DOD tag, as a rule, (originally) match on
GPWs and that the frame tag and DOD tag match on MBs. I have always
attributed this to different assembly line techniques. I imagine that Ford
had blank components which were assembled and then numbered or had numbered
engine blocks and blank frames and stamped the engine number on the frame
(or vice-versa) and then completed the process with a dash tag stamped to
match. Willys engines, on the other hand, don't match the frame or DOD
tag. Willys, apparently, numbered engines and frames seperately and
diddn't worry about marrying them up later. The dash tag, however,
reflected the frame tag number. I've never seen an MB with 3 matching
numbers. Although I suppose it is statistically possible, it's unlikely
and if it did occur would probably have been a slat grille. I say that
because engines seem to be used up about 25% faster than chassis (spares,
defects, pumps, gen sets, etc.) and towards the end of production the
engine and chassis numbers were 150000 units apart. (This is true for CJs,
as well, except for the percentage.)

I have owned quite a few Jeeps, at least 10 have been MN GPWs (still have
3), and looked at quite a few more. I always gravitate towards the
tattered originals, rusted or not, for what they can tell me. A few years
ago I placed an ad in MV magazine for just such "survivor" Jeeps. I got
amazing (some TRULY amazing) response, those I didn't buy, I documented and
nothing I saw there conflicts with what I've said above.

As for Auke's GPW, I'd say it is virtually, certainly original. I find it
unlikely that farmers are out in their fields restamping engine blocks to
get an extra couple of dollars for a rusty hulk. Even older restorations
or recent ones where folks aren't making a big issue of the numbers are
likely not messed with. Exactly correct stamps (numerals and characters),
to my knowledge, are not readily available. I have seen people with rusty
frames cut the number from the rail and weld it into a solid frame.
Probably not exactly legal but it is, actually, still the original number,
not a restamp. In my opinion, doing whatever would be required to do an
absolutely,undetectable job of restamping a GPW engine # , given the
present difference in market value between MN and NMN, would make as much
sense as counterfeiting nickels. Besides, there's a way to tell no matter
how well it's done.

I am interested to hear others thoughts on this. Surely, some GPW true
believer, Bill?, can tell us the assembly line procedure. Also, I'm
curious who actually did the dash plaque was it the Army rep or the
manufacturer? I ask because I don't know anything about military
procedures or military vehicles, in general, as my only interest is Jeeps
(quite a few happen to be MVs).
