It's taken quite awhile, but I finally found a nice, matching, unmessed with G.29/40 siderail marked. This one turned up in a pawnshop in Texas for $375. It is completely untouched, matched to the screws, never in collector hands. The bayonet lug had been removed, had the front band stuck halfway on it. When I got it I was pleasantly surprised to find that the lug pin had been placed back in the lug but the lug itself never reinstalled. It is my understanding that the lug removed reduces the length of the stock sufficience for mailing, like a dufflecut but without the permanent damage. More pics after I've cleaned off the cobwebs and air rust.
