Over 30 years ago, the original Victor factory/office buildings in Camden NJ were being cleaned out by their corporate owners, and a variety of wonderful stuff turned up in dumpsters outside the plant. I was not one of the lucky dumpster-divers but fortunately, others were on the scene and a lot of things were saved. Shortly after this incident, I was fortunate to acquire an experimental Victor sound box similar to a Concert, but never put into production. The seller told me that it had been found in one of the notorious dumpsters.
I can't say for sure if this shell for a Victor No. Ten sound box was among these items, but it's likely. Those familiar with these sound boxes will notice that this shell was never drilled for assembly, nor does it show any trace of gold plating. What I find most puzzling is the odd L-shaped piece mounted at the 6:00 position . If this was an experimental model for some alternate design, what were they trying to accomplish? Applying tension to the diaphragm (like the Higham)? An adjustable diaphragm dampener? I'd be interested in ideas.

If other photos are needed of specific areas, I'll be pleased to provide them.
