There is company in Tennessee that makes hard maple drum shells and
hoops, plus heads and hardware, in practically any size you would want.
Their prices look very reasonable compared to what I have paid for
original Wurlitzer drums.

I have not bought anything from them, and so cannot vouch for their
quality or business practices.
