Manufacturer: Aria Size: 14 x 5.5" (shell depth measured at 135mm = 5.3") Shell Thickness: 7-ply, 8mm (+ covering) Tension: 6 tension Lug mounting hole distance: 47mm Lug mounting hole diameter: 4.5mm Strain switch mounting hole distance: 35mm Strain switch mounting hole diameter: 5mm Butt plate mounting hole distance: 64mm Butt plate mounting hole diameter: 5.5mm This is an Aria snare shell. The bearing edges are relatively wide-shouldered, with a large contact area with the head. The wood type is unknown, but it's a 6-tension Japanese vintage snare, and I think it's a rewarding piece to assemble. For reference, I'll include one original lug that I found as a bonus.
