Here is more information ...
Gun was purchased in 1970 from a gun store in Germany. The gun dates to 1961.
Current owner has only used the gun a few times in the last 50 years of ownership.
In the 9 years before the gun was purchased by current owner, It seems unlikely that the barrels would need refinishing in such a short time.
These pictures do show some hard use on the front wood. Any ideas on the cause of such wear?
