In the late 60s a firm in Florida began offering re-barrel service. They had the bbls built by one of the Bernadellies in Italy. They would either build a set from scratch or strip your old bbls & use the parts, such as ribs, lugs etc.
I had a set built for an FE Lefever from scratch, still have them as well as the original damascus ones. At that time I was just on the brink of deciding I could actually shoot the damascus. I already had most of the facts concerning their use, but with everything one read from "ALL the Experts" it took some to make the step.
These bbls were made of Boehler Steel & bear Italian proofs, not that that really matters to me. Turn around ran a lot longer than they had stated, but did receive an explanation from them. They stated that some changes in custom laws required a Layover of some time & consequently due to this they were discontinuing the service as soon as they got back all the guns they had in Italy. I had been promised a turn around of 2-3 months but it ended up closer to 9 months. They finally came in late 1970. The firm name in Fla had Knight in it, but don't recall the actual name now. I would not say the quality of fit was as good as the original Lefever bbls but was quite good for the money. Don't recall exactly but was around $150.00.
The reason I chose them over Atlas was my gun was neither a Parker nor an L C Smith.
