[78-L] Victor NY Studio Locations

[Chris Zwarg]

I have spent some time extracting various dates from the Sooy Brothers' reminiscences as put online here:

http://www.davidsarnoff.org/onlinetexts.html

In their chronology of Victor studios (or "recording laboratories" as they were called back then) I notice a missing date for New York:

a) 26/03/1903 to 08/10/1904: New York, NY., Carnegie Hall, Room 826
b) 08/10/1904 to 05/1909: New York, NY., 234 Fifth Avenue
c) 01/06/1909 to ???: New York, NY., 37-39 East 28th Street
d) ??? to 19/01/1917: New York, NY., 22 West 37th Street
e) from 19/01/1917: New York, NY., 46 West 38th Street, 12th floor

Can anybody here enlighten me at which point in time between 1909 and 1917 the studio moved from 28th to 37th Street? Neither Harry nor Raymond mention the date.
