This is very much a project.  Despite what the seller says, I’m less certain that grille is stock.  It looks like a MB grille to me.  The body, along with the V35U specific data plate, appear to be correct.  Here are some pics I was using from the G503as a comparison.

“I am selling a VERY RARE military jeep. Here is an article on them: http://www.cj-3a.com/CJ-V35U.htm

It is a 1950 Willys CJ-V35-U. They made only 1000 of these jeeps for the USMC in 1950. It is factory built using a mixture of MB, And CJ3A parts, and is very very rare. The one that i am selling is in VERY restore-able condition, and mostly complete, and un-molested.  It has been stored indoors for several years.  This jeep retains a lot of the original, hard to find parts, like: Ram horn tow hooks, Starter, generator, voltage regulator, front seats, pintle hook, Fuel tank, front bumper, bumperetts, tail gate, lower spare tire carrier half, air cleaner, cross over tube, fording exhaust with shroud, head light switch, Transmission locking chain, all gauges (minus temp), two correct windshield frames. NOS voltage regulator, NOS fording tail pipe bracket.

It comes with the following reproduction parts: Upper spare tire carrier, Lift rings, and antenna mount. This is a NUMBERS MATCHING JEEP, the engine is the correct serial number for this jeep!! the engine number is V-10125, and the chassi is believed to be chassi number V-10115. They started production @ number V-10101, so this was #115 of 1000 to be built. It has the correct hood, fenders, grill, body. There is a little controversy over the nose of this jeep, but there are things i can point out that are factory and that no one would have been able to change. It is very early production in a very limited production run. Asking $5100.00, Sorry no trades”
