Can anyone identify these bolts? They look like bumper bolts. They are NOS.

If the heads are not offset, I think the 11A bumper guard bolts which fit all of 41 and 42 Deluxe. They may work on the 42-6 Super Deluxes but not fit exactly right. For sure NOS as the threads are different on the reproduction ones. The ones in my photo are correct for 42-46 Super Deluxes. 47-48 use a regular bolt that goes into the rear of the bumper guard.
