I would say from the photos that it is not a G&H "Depression Sporter". They typically did more reshaping of the wood and added a horn tip and removed the barrel band. I would also like to comment on the note that said it was unusual to have a perfect bore, I have a large number of sporterized NRA Sporters and they all have perfect bores. Unlike some issue guns, the people who bought the NRA Sporters and had them remodeled took very good care of them. It is a nice sporter and I would have acquired it if I had the chance.
