Interesting address. Remington Arms Co. ads in those days list their offices at 313 Broadway, NYC, as does Union Metallic Cartridge Co. H & D Folsom Arms Co. had premisis across the street at 314 Broadway, NYC.
Schoverling, Daly & Gales were at 302-304 Broadway, NYC. Von Lengerke & Detmold was at 318 Broadway, NYC. Also, Capt. A.W. Money had his offices for the American E.C & Schultze Powder Company at 318 Broadway, NYC.
What a block to visit back in the day!!
