This 1948 horn has a decent collection of small dents, but I didn't notice any major structural issues from the photos. It has a removeable curved bell, but is otherwise configured like the standard Bessons. The starting bid is $325 and the buy-it-now price is a reasonable $499!
Starting bid was lowered to $350 and it sold for that price. Wow!

Below the photos here (more can be found in the listing) I have included a blow-up of the valves, which don't appear to have excessive wear.
