I have an old IRC volume control catalog from '41 that has a cross-reference. Here's what it says for the 310A:
Majestic (Grigsby-Grunow Co.) 311 (310A)
Volume - model J-165 - 200M ohms - Mfr's part no. 7236 - Rider's III-21
Used on Majestic models: 77, 291, 293, 294 (290), 303, 304, 307 (300), 311 (310A), 314, 315 (310B), 324 (320), 331, 336 (330)
Maybe you can find a pot from a parts chassis. Best of luck - its a nice set!
