Potentiometer identification

These have been floating around my junkbox for a number of years now and I think they are destined for eBay, they were given to me and I have no idea what brand or model of amplifier they were from.

Does anyone recognize the knob design? One clue that might help. I have an output transformer probably given to me by the same person and it was meant for a quad of 6L6 tubes.

You trying to sell the knobs or the pots? The knobs appear to be common "chicken head" type. Though the color is unusual.

I don't think having the pots around helps sell them. I assume the knobs have set screws? And 1/4" shaft sized?
 
I still think you'll get better traction selling them separately, but that is just an opinion.


However, we cannot identify the pots without seeing them. All we know is they are bolted to common chicken head knobs. And even though they are obvious pulls, it would still be good to clean the solder lugs of old solder and wire bits.

We'd want to see the sides and/or rear of each pot. Should be numbers printed or stamped in the metal there. I would certainly recognize old Fender or Peavey or Crate part numbers, and others here likely know other older brands.

If you think the transformer came from the same unit as the pots, what part numbers are on the transformer?
 
Alright some details. Numbers stamped on the sides and measured resistance:

134108 RV-42 (1M with tap)
134015 RV-41 (500K)
134015 RV-40K (10M)
134015 RV-41 (500K)
