I saw in the code that pic being taken in 1949. Makes sense - the RCA meatball logo variant in the front looks like it first came forth around 1944 or so (plus, pre-December 1942, the company administering Victor known as RCA Manufacturing Co., Inc.). 'Twas in the same year this photo was shot - '49 - that the RCA Hollywood plant began using Bert-Co to do their label typesetting, rather than getting it from Camden or Indianapolis of wherever the bulk of label type on RCA releases was done in those days. And a few doors up from here (at 1032 N. Sycamore), was the then-Radio Recorders Annex that later became Annex Studios. Of course, by then Goodman had gone first to Columbia (in '39 - I have a few of his records from there including the very first "red label" issue of Columbia as we know it today, #35201, "Comes Love" / "Rendezvous Time In Paree"), then to Capitol. I seem to recall all RCA studios including Hollywood, as of '37, using an early version of the Scully lathes built between 1934 and '37 that were later sold to other recording companies (from 1938 to the late '40's) as the Model 501. It would have presumably been that equipment on which these Goodman tracks that are the foci of this thread were first laid to wax.
