I don't consider "parts mismatch" the issue or point of danger.

I am apprehensive about making a recommendation about firing these Bannerman 'salvage Krags'.

The guys that cobbled them together certainly were not going out on a limb in 1914. They were not guaranteeing them!

The Bannerman catalog page description is kind of scary with vague mention of "fire damaged parts" and re-tempering.

Maybe the quality of parts improved, on later Bannerman Krags that used altered 1903 Springfield stocks.

I'm not a 'shrinking violet', but, some guns are 'too iffy' to risk my life, limb, and 'movie star looks'.

I would want an "experienced hand" examining this one, directly.
