Internet deal...........scary....
Concern being that the inletting issues, or lack of inletting, could be indicative of other inletting issues.
My trigger guard and side plate wouldn't be bad on their own. I didn't notice them when I 1st agreed to buy the gun, and might have anyway.
not real noticeable.
More noticeable, but correctable, but twisted also.
Unfortunately these were indicators of problems elsewhere. Again, that I didn't notice at 1st.
note that flint and frizzen do not line up.
Pan cover/base of frizzen does not meet side of the barrel.....
See the shim? I'm assuming the lock was inlet too deep. So, the builder of this kit shimmed the lock out leaving the gap between frizzen and barrel and misalignment of flintcock and frizzen.
But wait, there's more,,,as Billy Maise would have said...
Sear bar and top of trigger are also shimmed.
These last two are fine, they are what they are and offered a simple and effective fix for what would have been at best a horrible trigger pull and at worst a completely nonfunctional trigger.
But that shim next to the pan is a problem I'm not sure I can deal with myself.
All I'm getting at is that the small issues (small depending on how bad that crack really is) seen in your pictures could be signs of bigger problems elsewhere.
