[JMS] 90801 knobs

Sat Feb 7 22:45:35 EST 2009

Don,

The 90923 does use the bar-type knobs but they are larger than those  
on the 90801 and I bet they are the same size as Bill just found.

My 90801 bar knobs are 3/4 x 3/8 x 1/2 high; same size as the A001  
knobs in the Millen catalog. So it would appear that SOMEone made  
these A001 knobs for both 1/8 and 1/4" shafts.

These "mysteries" are always fun to sort out - hi.
