This is a Gretsch drum that purchased a few days ago. I don't really know anything about the drum. Can you guys give me some information about this drum. I would like to restore it, but really don't know how to go about it. I took a few pictures of it. The wrap looks good but when you take them rim off it has some sort of dark stain that runs along the rim. Can this stain be removed? I noticed that seam has lifted, I guess this can be easy to repair, if you know how. Please give me some info on the drum and advice on restoring it, if it's worth restoring. Thanks,
