WTB S&W .32 Double Action 4th Model Cylinder Stop

[gmwagner]

Hi All,
I am looking for a cylinder stop for my 32 Double Action. I went to my usual go to, Gun Parts Corp. Their web site indicates 'Sold Out'. Oh boy, I treat this as a 'bad' sign. Can anyone offer a suggestion for a parts source?

This is a wishful thinking type of request, I know. I would appreciate any assistance.
