South Bend 9" , Clausing, Atlas other 127 tooth Metric Change gear set

Description

Have had this change gear set on the shelf for years, came from retired machinist and could fit several early lathes, but I believe he was mostly a South Bend guy.  The popular 127 tooth gear is Boston Gear with a 3/4 Bore and the other two gears are a 44  with shoulder (apprx 1-1/4 thick and bushed to 5/8 inch) and a 22 tooth (bushed down to 1/2 in)  Gears appear to be excellent if ever used at all.  Other than tooth count or more pics cant be very helpful as far as what else they will fit.
