I have a 1941 Willys Slatgrille (spelling unsure). I know nothing about where it was or the serial number or any of that because When i got it the data plates were gone along with the rest of the body thanks to rust. Not my fault tho. all i have is the frame number but i wil soon have the engine number on there. if anyone knows where I can find out information on ths jeep please email me at chris45auto@yahoo.com. it would be mucgh appretiated and would help me. I plan on putting my fathers numbers on there because I have a picture of him sitting in a slattgrille in europe during the war. Right now its in my garrage due to a lack of budget since i also have a 1944 dodge weapons carrier and a 1951 willys M38 that my grandson is restoring at his place. for 14 he knows alot about this stuff. maybe i can get a picture on there sometime or another.
