[78-L] RVCA instead of RCA Victor?

[78records at cdbpdx.com]

I have several Victor/RCA-Victor records and they show many iterations of the Victor and Radio Corporation of America name after the two companies merged.  Here is one I haven't seen before:

VICTOR TALKING MACHINE DIVISION
Radio-victor Corporation of America

RCA Victor might have become RVCA..??

Where can I go to find all the company name varieties?

Thanks!
