Franks's Drum Shop perhaps?

I have that identical pedal -except that mine says "WAMCO" on it -which stands for "Walberg and Auge Manufacturing Company". It has aluminum components on it...so I THINK that makes it post-1930's...but I could be wrong.

O-Lugs, you are quite right. On the underside of the footboard there is a WAMCO mark. Perhaps the pedal was made by WAMCO for Franks's Drum Shop?

Did Walberg and Auge make these pedals for Slingerland as well or is it just the same design as the Slingerland Krupa #836?

I really don't know much about vintage Slingerland.

In the early days, Walberg made the hardware for Gretsch, Ludwig & Ludwig, WFL and Slingerland. Camco made it for Rogers (pre-swivomatic era of course) and later Slingerland, as well as for Geo. H Way drums (later Camco themselves). Leedy was the only drum company to manufacture their own hardware. They did everything in house. Walberg was the biggest manufacturer of drum hardware at onetime, before the manufacturers started making it either in-house or farming their own designs out to someone.

I would agree its a Walberg stand made for Frank's Drum Shop. Frank's had that kind of clout (and large customer base) back then so I'm sure it was a possibility.

"Feminine Deoderant Spray"

I was wondering who would finally say it........
