[GreenKeys] Need TT Pinion and Gear (305043 & 305044) for auto answerback unit (LABD)

[Russmill47 at aol.com]

They are also known as a Gear set as 305047.
 
These are gears for a self contained answer back unit (LABD).
 
I've tried Fred at Typetronics and came up empty.  If you don't  have these 
parts,
is there anyone else whom you can recommend?
 
73 and Merry Christmas,

PS:  Do any of the M28 fanatics on here remember the answer back unit  that 
mounted inside the M28, in front of the LP?  If so, what was that  answerback 
unit called?
