I am out of my area of expertise with this particular project.
I am needing some assistance with identifying this drum. Unfortunately the attached pictures are all I have to work with at the moment.
To me the most interesting feature is the use of L-angle pieces mounted directly to the wood hoops for tensioning the heads. The tube rods offer single tension, which was also not particularly common in early marching drums. There are also many more than the typical eight tension rods per side. I keep counting 15, but hope that I am just not seeing the 16th.
The only drum I can find that had more than eight tension rods per side (it has ten) and used the L-angle piece in lieu of clips or claws is a 1930s Slingerland Artists' wood hoop snare that Mark Cooper has shown on his website. I include the picture of an advertisement which is found at http://www.coopersvintagedrums.com/newslinghistory.htm (about 20% down the page).
There seems to be some interesting artwork near the vent hole, but I cannot get a straight-on shot of it.
Any assistance in identifying this drum will be appreciated. I will not see the drum in person for a while and I these are the only pictures available right now (I know that pictures of the throw/strainer and the interior of the shell would help a lot.)
