Yamaha drums ID

I bought a set of Yamaha drums in 1987-88 the inside of the shells are black. I re-wraped the kit several years back and being stoopid, I took the id badges off. what I can remember, the badges were a square and had a V on them. If someone could help me, Thanks. I know that Premier made Yamaha for a while. what might they be worth?

Probably a Power V. Did the badge look like this?
