In addition to the two boxes mentioned in the 'layshaft end float', I scored an ok empty case, except for the sleeve gear still intact- rubber mallet- no way....heat on the bearing inner+sprocket nut for protection and soft thing and a drift with a 10 pounder- no way...
Had to run a length of 12mm booker-rod (threaded rod) through with plates and packers to support the sh, and after a great deal of effort, it cracked- though I'd busted something but was ok seems they sometime have a raised bit around the ends of the spline that make the gear tight in the bearing
This is not really stamp related, but it is to Mettys story- probably need a different topic for it
