Any chance of posting some of the pictures here?  It's hard to give a decent assessment of a Krag's value without being able to see it.  It may be sporterized, cutdown, or otherwise altered and a novice might not be able to spot the modifications.  An SRS hit is great, but due to the loss of the majority of the records, hits are few and far in between... and a hit (or lack there of) doesn't mean that the Krag is not a great purchase or value.

What is the asking price? Unless it is awfully cheap, you can do much better. Look at the offerings on (You need to Login to view media files and links)

That is a pretty rough Krag, and the late seller, whose business is being liquidated by the family, had a VERY bad reputation with regard to trapdoors.

Bingo - and, that is not an "original" Krag - the metal (receiver) is at least two years off the stock date, so it is no blushing virgin.

That firm's trapdoor business was (is still?) well-known for assembling guns from parts - in at least one case (known to me because I was a witness in the court case) with clear intent to defraud.

Am not saying every piece they have is bad, just that they have a bad history, and purchases should be carefully scrutinized.

I personally would not pay anywhere near $650 for that particular rifle, and would strongly suggest patience and further research.
