on those locks, if you polish the
end of the mainspring that bears
on the tumbler,(with a muslin wheel & compound)[size=78%] [/size]
and just barely and very carefully
polish the surface of the tumbler
that the mainspring bears on,
and do bare minimum clean-up
on the sear surfaces, it won't
even feel like the same lock.
i'm glad you got that good deal.
i got mine from a guy who decided
he really didn't want a black powder
gun after all. with almost a full pound
of powder, and a box of bullets minus
six, and a tin of crappy caps.
i have way better mzlloaders, but to
hunt in the drizzle, or as a loaner, or
what have you, a better rifle can't be
had for that money.
good luck with it.
