The flattie looks to be a M-38, so the year should be 1950 or later.  The other I’m guessing to be a M-38a1.  It’s a bizarre parking job.

“The red jeep ran when i got it 5yrs ago. The drive train worked good too. It has a title. The yellow jeep has the motor taken out of it and is in the back of it same with the front clip. The drive train is good on it though. It dosent have a title. I was gana take the two and make on nice one. And take the rest of the other one and make a trailer for it. I will bring them to denver for you for an extra 300. If you have any questions feel free to ask @ mrdobrinski@gmail.com”
