Dave, I have been thinking on the 253 Church St. address and can only guess that it might have been a separate higher end mostly guns store. Of course 1929 was looming ahead and I don't know how soon Folsom might have felt the warnings of that. I see the Church St. address in my papers from 1923 thru 1925 at least. 1927 seems to have Baker Guns back at 314 Broadway.
