UPDATE: Dexter was correct … this sports a slat grille.  He also provided some additional info and a pic.

The seller sent the following to Dexter: “This jeep was purchased from cousin in Idaho seven years ago. • It’s been sitting outside, covered, for the past year • The frame number is II3056 [Dexter comment: I see a dash before the 3, but the folks at G503 tell me it’s the 13,506th slattie made] • No glovebox type, with no data plates on the dash • Cousin, Bubba, removed the entire back (With the original WILLYS stamp!), and replaced it with sheet metal • It has body lift • Gas tank moved to the rear seat • He doesn’t want to get rid of it, but his wife has spoken.  The block is cracked.”

“This is a 1942 willys jeep in fairly good condition…..the motor in it has a cracked block. it runs but bubbles in the radiator. I have the original flat head four cylinder motor that was smoking when removed probably bad rings. This jeep has been sitting for a while but DMV is current non-op. call anthony at 593-5074 if interested.”
