Cap Lock for Muzzleloader Percussion RH lock , as new , Jim Chambers ? As new in the white

Percussion csp  lock ,

as new never used ,still in the white, was ever installed. 

Jim Chambers lock ?

It is a quality lock very quick and smooth.

I bought it , thought I was going to have to replace a Kentucky lock but i was able to clean up old lock  and tune it up . 

So this is surplus to me right now, maybe someone else can use it?

They sell for double this from suppliers

Asking $150 +shipping or maybe trades?
