Hey y'all. Got some questions for ya.

I am beginning to restore what I thought was a Rogers XP8 kit in silver wrap. Got the heads off, and the toms have flat bearing edges on the bottom, although there are lug casings & rims for both top & bottom. A local drum guru advised that the drums likely began life as single-sided/concert toms and were 'converted' to double-sided at some point. The shells appear to be 8-ply maple, though, with no re-rings, and the set came with a Rogers XP-8 front bass head. It screams XP-8. So....my first question is, was the XP-8 series available in single-head configuration? Regardless, I will be having bearing edges cut into the bottom sides for the rebuild.

Secondly, the silver wrap is coming off fairly easily, but I'm at an impasse with the vent hole/Big R logo. The logo appears to be no more than a sticker applied to the wrap, but the grommet won't let go of the shell. The grommet doesn't appear to be the kind that passes all the way through the shell and has to be crimped/ruined to remove (see pic). How do I get it out?

Any input is appreciated!
