what i have does not appear to be a reproduction.
it has the lowered radiator mount pads with elongated or oval holes as Fred stated, and the hole to the left side to receive a radiator overflow tube, Marco.
the frame is stamped A922804 just as the cracked block, the firewall is 8-18-29. this parts pile is titled as that.
Les's volume 1 book states what i have to be a " '30/'31 recessed" on page 1-238 and what i should hope to find " '28/'29 raised"
since there is a third later . i'll make a note of that in this book and detail it's difference. thanks Barners.
here is an ad very similar to what i've got, minus the rivets at the crank hole mount area.
