The guns have been produced for many years, and by more than one manufacturer-a few were built in Czechoslovakia. Anyway, SOME have the barrel band at the front and some do not. SOME had a plastic barrel band, which, has been happily discontinued. You can look at Roger Barlow's photos of his guns to discover this for yourself.
You either need a lightweight 12, with two shots on tap, or, you don't. I'd use this before I used a Winchester model 24. Especially if I ever get my chance at Himalayan snowcock, and I 'gotta lug my gear and my gun at the same time.
What is recoil like? Here's a hint-look at the recoil pad and the cushion behind the trigger. Both were attempts to make the recoil managable for some poor soul. Some of todays low noise and recoil stuff might make it tolerable. But, it is what it is, and that will never be a "100 rounds of skeet at the club gun".
Good luck on selling it, by the way. You are a bit out of your market. You knew that.
Best,
Ted
