Looking at one that must be 1950's-60's (they went out of business in '69 I believe?), trying to decide if this is rare enough to pay attention to, or if you've had any experience with one this late? Their late 19th/early 20th c. clarinets have incredible craftsmanship and materials. I wonder if they actually still made their own that late, even? It looks a bit like some Couesnons of that era, but the bell looks to have a bit of a crystalline resin structure, like a phenolic resin, while the body is wood.
