A 33 Box should have a 4 speed crash box, which are usually pretty sturdy. Has it been fitted with a later synchromesh one as they are not... A crash box has a big nut on the forward end of the gearbox cover.

The lateer synchro boxes do suffer wear in the layshaft due to worn thrust washers. This could be the source of your noise.
