My guess, looking at the 1941 and 42 product cut sheets, is a 42-RP2, since the case is smooth, the 41-RP2 has a moulded front on the lower case. Circuit-wise they are almost identical, between the 41 and 42 versions. Case may also have been refinished at one time, since the photo-finish "veneer-inlay" strip is missing on the lower case.

{EDIT, later that same morning.} Ok, maybe not.......
