here and there I read about a Precision Scale retainer valve being the ultimate part to use next to a brake wheel and housing on our precious HO-scale cars.
However, I can't find exactly which part number it is, brass and plastic are used in various topics
Plus in my old PSC catalogue these are parts for tenders...
Can anyone supply the part number please?
I'm modeliing 1950, so mostly AB brake and some K's.
Thanks & regards, Fred Jansz
