the R1556 designation came from the RAF. So you won't find anything about the modifications in either the RCA manuals or EMERs. EMERs were specifically British Army documents.

There were quite a few variants (and sorry I don't know anything about them): R1556, R1556A, R1556B were covered by A.P.2567A, and R1556C was covered by A.P.2980K. I've not seen copies of any of these docs, but no doubt someone will have a copy.
