It had obviously been "re-purposed" as it had a pulley pressed on to the input shaft and a fair bit of sawdust inside! I guess a lot of crash and 3/4 boxes were replaced when 2 Syn became available, hence they are often in great condition. Some time around 1933-4 the selectors changed from cast steel(?) to bronze, not sure specifically why, but I robbed these from a later box.
Unless it had been used to drive a woodworking machine with the top left off, the sawdust might have been that old trick of making it run rather more quietly....
