I am not real familar with these, I don't own one. Looks like a paco pad, but in the glued on square that typically (I assumed) has the Jacks Plastic Welding info, the square actually has a shop's name and phone number. I am going to call the shop to see if this was a rental or if they have any record of who might have bought them from their store, but if the owner can clearly identify I will be happy to coordinate its return.
Anyone know where else besides the buzz I could post this on a lost/found board? I would actually feel guitly keeping this thing, I know how expensive they are. Later.
