[MV] MB/GPW (no question mark)(?)

Hello MB/GPW folk
(and other interested parties)

Deep breath -- as I warned last month, I'd be posting for info on my jeep
(and thanks to those wh've helped already). My "problem" is that I seem to
have a MB/GPW hybrid. (I should say here that I do not, unfortunately, have
the data plates which should be attached to the glovebox lid.)

I've studied the excellent FAQ by Jim Rice on the differences between WWII
jeeps and early CJ jeeps (which also gives lots of differences between MB &
GPW). I've also read Todd Paisley's equally good "Differences between a
CJ-2A and an MB". I've even had a peek at some pages from the All-American
Wonder (thanks to Robert de Ruijter).

My jeep (the Miss J) has, among other things: 2-bolt spare tire carrier;
pintle hook; 2-piece windshield; toolboxes in the reare of the wheelwell;
'doghouses' on the rear floor; indents for axe and shovel; on the LHS; gas
tank filler under the seat; headlights on swing brackets; semi-circular
section in the floor riser for machinegun; carbine holder brackets (no
holder) below the glass on the windscreen, etc.

So I'm positive I have a wartime jeep
(although my registration says it's a CJ-3A -- it was imported into Ireland
from England a few years ago and that's what the documentation says...
Anyone got any theories on that?).

What I can't say for sure is whether it's a GPW or an MB.
On the GPW side, it has the inverted U crossmember below the grille, with a
script F stamped on top, visible through the grille. (The F is a bit rough
looking though.) Also, the serial number ison top of the left frame rail:

On the MB side, everything I can see about the body is Willys -- the
toeboard gussets have five round holes instead of two round and one oval;
the toolbox lids do not have embossed ribs; there isn't a script F anywhere
on the body or bolt heads.

So for, so clear. But from underneath, the Black and White gets fairly gray.
Y'see, I've found the following part numbers on the engine alone
(please forgive my lack of technical descriptiveness...)
On top of the cylinder head, it says:
Order 1-9-4-2
Clearance Engine Cold
***** 014 Exhaust 014
with 'Willys' & 'Jeep' stamped into it,
so it's a post-war cylinder block, but, at the bottom right of the engine
block there's the letter 'M' beside a screwed-on plate which says 'A 9522'.
The number 5 is also embossed at an angle on the right side of the block.
Then, just above where the 'floating oil intake and pan' is attached,
there's 'GPW-6015'.
Is even the engine a hybrid MB/GPW/CJ?

Other numbers I've seen are: GPW 6616 and (on the clutch pedal bar) A 406.
An original MB manual TM-10-1513 came with the jeep, but I can't identify
those parts. The manual says the clutch pedal bar should be A 405.
Also, on what I think is the transmission case there's WOM A-1149, with a
triangle and a 2 below it, but, again, the manual says the transmission
case is A-1148, with no mention of WOM, or what it may mean.
There's also a part, GPW 6616, which I can't find in the manual either.

So finally, to my questions (and thanks for sticking with me this far!)

-- What do I call my jeep, an MB or a GPW, given that the important 'bits'
seem fairly evenly divided between the two. Although I'm perfectly happy
with the beast and don't really mind calling it a hybrid, I wonder what the
'official' line is, since mine couldn't possibly be a unique blend.

-- Can I be reasonably confident that my jeep is of WWII vintage and not
just thrown together from old warehouse stock after the war?

-- Can anyone supply any background info given the frame number, 90216?

-- Is the engine itself a hybrid or does anyone recognise the combination
of numbers described above? In documents from the UK going back several
decades, the jeep is called a Ford, then a Willys, and the engine size has
been listed as 1600cc, 1800cc, 2000cc and 2200cc. Which is, or could be,

-- Any reason why the designation on the changeover from military to
civilian use might be CJ-3A?

-- Can anyone help with the numbered but unidentified parts?

-- Between the glove box and the instrument panel, there's a 1.5 inch hole
in the dashboard metal, with 4 smaller holes placed in a rectangle around
it, total size about 6 inches by 2.5. There's also several other holes, for
other items mounted on the dash. Anyone know what should go into these

Thanks in advance -- hope I haven't broken any List rule on length of postin=
