In the 1939 Polk Directory (San Francisco) The Pacific Gun Sight Company is listed. Its address is given as 353 Hayes (error?). It is pretty close to 355 Hayes!

In 1939, Robert J. Miller and Robert S. Miller are at separate residences. (Likely son Robert S. got married). Both men are listed as connected to the Pacific Gun Sight Company.

In 1939, Walter J. Sutton is listed as a 'mech.', but, no connection is any longer shown to the Pacific Gun Sight Co. or the Millers.

FWIW - In the 1938 Polk Directory, I can find no Listing for the Pacific Gun Sight Co. That year, Robert J. Miller is listed as a 'Gunsmith' operating at 355 Hayes Street.

My hunch is that around 1938, possibly, Walter J. Sutton was bought out and the Millers legally organized things as the "Pacific Gun Sight Co".
