It's interesting how a second spit key materializes in one of the pictures -- ostensibly all of the same horn. If anyone is interested in one of these, I have a similar one -- 1934-vintage -- arguably in better shape that I'm willing to sell. Same gold wash in the bell and all original (including the case) except for a re-created lower mouthpiece receiver where it comes out of the valve block and loops over the upper set of slides. Kevin Power at Custom Music refabricated it and salvaged and reused the original bracing. This is a horn with lots of interesting features in that it has spring-loaded spit keys on the bottom of each valve and the bits and upper part of the receiver have a threaded locking system to secure them once adjusted. Each of the bell screws had an integral set screw. Lots of interesting little features like these and a the case features blanket that fits between the bell and the body and little straps and fittings to accommodate each of the mouthpiece components. Original, hard-to-find mouthpiece (two, actually) with the largest shank size that I've ever seen. PM if interested and I can supply further details.
