6.5x14 "Big R" Dynasonic. This drum is in nice shape. I haven't touched it. There is just a bit of grime on the top hoop and some fingerprints, but the shell is very clean. One small spot under a lug where you can see the brass. One of the lugs is just slightly indented - you have to have the drum at a specific angle to see it (lug directly to the right of the badge). Drum is complete with bridge assembly. Please see photos and PM or email me at [email][email protected][/email] if you're interested or have other questions. $550 OBO. SOLD
