Don't know about Mallory. I did some further checking and the schematic that Riders shows as the "46-200" is actually the CODE 125 version of the 46-200. My Production Changes for the Code 125 version reflect the two 14 volt tubes and omission of R100 in the fil string.
Your set, with that tube complement, is a Code 122 version. The changes from the original Code 121 are only the rectifiers and filter cap and the addition of dropping resistors R101 and R102. This permitted the use of a PM speaker. The new three section filter cap and two resistors were added because of the field coil elimination.
