L & R replacement locks: Good or no?

[Niederlander]

Hello the camp!
     Have any of you gentlemen used an L & R replacement percussion lock?  If so, how do you like it?

[Tascosa Joe]

I haven't used one in about 30 years, but they were good in the old days.

I have installed two in T/C guns. They are of moderately good quality, and fit the lock mortise with minor wood removal. At least you can get parts for them if you break something.
