Whig: I am not an owner of an early Krag, nor do I have access to one, to study firsthand.

I do see the work of a lot of craftsmen, who build very nice traditional muzzleloaders.
If such a builder put his mind to constructing a replica 'early U. S. Krag' and had some good original parts to work with, I am sure a Krag, such as your new one, would be the result.
It is very ethical that no markings were put on the stock.
(FWIW - It appears to me to be a recently made stock).

I think the front-band on your 'new' Krag is skillfully altered. There appears to be a weld or seam, where the 'tube' for the cleaning rod is attached. The inside contour at the 'tube' is a bit off - (sharp cornered instead of rounded).

I do very much like this 'reconstruction' and it is good that you knew it to be so.
