Kibler SMR finishing question

[ScottH]

Those of you that have finished a Kibler SMR kit. How did you finish the lock?
I'm at the point that the stock is almost complete with finish on after staining with iron nitrate. I cold blued the barrel, trigger guard, and butt plate. Now I have to decide what to do with the outside of the lock.
Thanks
Scott

In our class we buffed up the parts with a scotchbrite wheel then torch blued all of the parts except the frizzen (which got cold blue) and cooled the the parts in used motor oil. About an hour’s work.

Here are two Kibler SMRs with browned furniture, for your comparison.

I don't know exactly which parts of Kibler's locks are cast, and which are machined.  If you haven't yet, you should file and/or sand all cast surfaces and machining marks that are visible.  When sanding, use the sand paper with a hard-backed surface.  Don't use power tools for that process.  When you do, it looks like you used power tools; and that just doesn't look right on a nice longrifle.

Used Cummins oil heat did not touch lock plate -sand polish just colored .
