Selmer 507. A superb instrument. Click on the picture for a larger view.
4 braces. Still a nice (crank ) on the top. Great singing tone. Big chunky walnut neck, deeper than 861 and a few millimetres shorter and not quite as wide.
I was told it was bought by a dutch player in December 1939 or january 1940 from the Selmer shop in Paris.
