The 13 has bigger venting holes (and badges) done by a previous owner. I decided not to further mess with the shells and did not attempt to close the wider holes. Other than that, the shells have the original bearing edges and no other issues or modifications.
Used drumheads but in good condition.
All shells with original scandinavian birch veneer inside.
It will be shipped in two boxes and some of the hardware will be removed, which you will have to install it back yourself.
