[Healeys] AEC3475 Laygear?

I don't have the exact details to hand for this particular part but you 
might be interested to know that on early gearbox gears and maybe later 
ones the part number on the item is not necessarily the service part 
number.

Often the part numbers are close.

The number on the part may be a casting or blank number or perhaps a 
gear without bearings fitted.

Stages of manufacture would have individual part numbers with a number 
for the total assembly. If it were only the total assembly that was 
serviced this would be the number in the parts book. The number on the 
part may still be a blank part number.
