This could be a Beck top.

“1953 willys cj3a jeep. clear ohio title. runs and will drive but master cylinder failed, so no brakes. I don’t consider it road worthy even though it does run and drive. needs a total restoration and will need a replacement body tub, fenders etc. does have newer tires and tubes on repainted rims. Nice thing about it is its all original drivetrain, flathead motor etc. has rare optional heater unit. comes with extra parts too. If your looking for your next restoration project this is a good start. will need to be towed. asking $1,400”

This may come with a second l-head.

“1950 Willy’s flat fender jeep with artic top . Has been sitting for the last 20 years in a field it does roll. Have extra motor with it, the jeep is all original has not been touched. would make a good restoration project, it does have some rust and a couple of holes in floor.

UPDATE: **SOLD** Was $2500.

Has updated engine. That might be a Porter & Reed hardtop, but I am not certain.
