33-35 Chevy I think. I had one that had that same mesh insert, but really rough. Was told it was from a '35 Chevy Master but that it'd fit a couple years earlier. Probably want to google some pictures to double check but I'm pretty sure that's what it is.
Here is a grille that came with a 34 truck cab i had, looks real similar. The lower splash pan just unbolts.
It's in excellent shape other than it being yellow and there are 4 inch squares cut out of each side corner. Easy fix.
117harv shows the fender ears on the bottom of his. Reminds me that mine had the same. Was your trimmed off? Maybe we're off base.
Are they a part of the grill that would have to be cut off? I'll check later. A buddy needs a few bucks and offered me the grill. I don't really need it but heh, to help a buddy out.
If memory serves the were part of the bottom grille surround. If I had held on to mine I would have trimmed them off for my application.
Definitly Chev Truck, the master series had the Chev emblem on the Grille itself a few inches down below the top of the shell.
