Hi,
I got these from my good friend and fellow collector Mark Cooper. Marl passed on in June of 2024. We did some great deals over the years and I cherish the many rare snare drums that I got from him. RIP my friend.
1933-34 SLINGERLAND 5 x 14 NOB DuALL RADIO MODEL
and
1933-34 SLINGERLAND 6.5 x 14 NOB DuALL RADIO MODEL
A brief history:
As a simple comparison the Slingerland DuAll parallel mechanism is very similar to the Ludwig & Ludwig Super-Ludwig parallel mechanism. Slingerland purchased the patent from C. G. Conn in 1933. Ludwig & Ludwig sued Slingerland for patent infringement and Slingerland was forced to cease and desist any further manufacturing of the DuAll model along with having to pay for any DuAll models that were previously sold. DuAll models are very rare and only appeared in the 1934 Slingerland catalog. This is totally unscientific on my part but in my 30 years of collecting I would say that the ratio of DuAlls vs Super-Ludwigs is 1-100. The Radio Model DuAlls are even rarer. I welcome any other viewpoints on this.
For a more detailed explanation of the Slingerland DuAll and court rulings refer to Rob Cook’s The Slingerland Book:
First edition pages 36, 184.
Second edition pages 33, 34.
Third edition pages 34, 180.
The NOB shells are in great shape and polished up nicely. The hardware is all original and also polished up nicely. The DuAll mechanism on both drums works perfectly.
Of-the -era calf heads rounded out this cleaning/restoration.
Enjoy!
