Identify and Replace Rotary Switch

Hey folks,

I've got a rotary switch I need to replace, and am having a hell of a time finding out how to replace it. Anybody have any ideas? If my switch terminology is right, it's a 2-deck, 12-pole, shorting switch. The schematic says "4-gang shorting switch". Thoughts?

From the schematic, I would describe it as a "Four Pole, Four Way" switch.

You imgur links do not work for me.

I can usually find what I need from Grayhill.
4 pole 4 position.

"Shorting" also means "make before break" which is typically used in audio switching so you don't hear pops.

Farnell stock parts to make rotary switches. (Shaft assemblies and wafers.) You could use 4 of these wafers. https://uk.farnell.com/nsf-controls/ma112s-454623ma/wafer-ma-1pole-12-pos/dp/146057?ost=MA112S
The manufacturers part number is MA112S. On the manufacturers data sheet they also list MA206S (which is 2 pole 6 way make before break) but Farnell do not seem to stock them. If you could obtain them you would only need 2 wafers. I think the shaft assemblies have adjustable stops so you can set them to 4 position. Another point. I would check the values of the carbon composition resistors. A few weeks ago I was looking for a resistor in my stock and found that almost all of this type of resistor had changed value by a large amount.

This look alright? https://www.alliedelec.com/electroswitch-inc-d4g0405s/70152224/
