I looked at (San Francisco) Polk Directories for 1936 and 1939 (online). This provided some explanations and clarifications.

In 1936, Walter Joseph Sutton, residing at 524 24th Ave. Walter is listed as a 'mech.' at W.J. Sutton & R.J. Miller, "Guns" business at 355 Hayes St. (This is the later address used by the Pacific Gun Sight Co.).

Robert J. Miller, Mgr. and Robert S. Miller, Sec. live in a residence at 682 Twenty-fourth Ave. (This is the address that appears on the Sight Instructions at the very start of this thread).

It appears that in the early days, the Millers' home address was used as the company's mailing address.

In the 1936 Directory, there is no mention, that I can find, of the Pacific Gun Sight Co., (although, catalogs and products bore the Pacific name).
