I was headed towards bringing up the 12-24 and then see you already mentioned it.

I may still have a box of 12-24 brass screws. I had a central office style 19" rack. Two vertical rails and really heavy base. Left that dude behind when I moved to Texas. That held the 2 meter transceiver, motor time out relay and power supply for the TU. Probably some other stuff I've forgotten about.

Motor mounting plate in Model 15 as I recall. Now 10-32 is familiar to hams and electronics

people because it is the standard screw size for rack mounting. But 10-24 is the more common

bolt thread in that size. Western Electric uses 12-24 for rack mounting.

Hadn't run into the 8-36 in any 28 stuff so far, is that more of a 12/14/15 era useage?
