The tubes for this Damascus sxs were made and not out of old stock according to the Purdey Manager I had the pleasure to talk with. They've been making Damascus O/U's for some time but this was the first Damascus sxs they've made in many, many years and they were quite proud of the result! It was sold within one week.
Enclosed is a pic of some very old Parker single barrels for trap guns made years ago under a Meriden contract with a French firm. Took this pic while in Paris.
Can anyone guess the gauge? :
These barrels were actually captured by Napoleon and brought back from Russia
