Looks like a great price. Seller believes this was the first year of the 3B.

“This is the first year of the HIGH HOOD CJ3B .has extras . needs the fuel tank. and voltage regulator. runs new brakes.[ 3500 OBO] text me to view. ask for CJ on text. has another windshield. BTW I have a 1992 garage kept fantastic condition Klamath 14 dlx Boat w/15hp evinrude for sale too[ 2800 OBO]”
Confused first and last year of cj3b?
Looks like a M606 with the ventilating windshield (missing some parts) and the pintle hook and the military data plates on the dash, could be a clone. 1953 was the first year for the Cj3B
Looks like this has a gov plate on the dash, which may or may not be a military.
