I have yet to play my kit. I bought it with other items for I think $200.00. 12, 13, 16, 22. The bass drum has a punch in the shell, repairable and on the bottom of the drum, so no big deal. Someone tried to refinish the set, but didn't bother to remove the outside badges, the insides have a small paper sticker and a serial number. Unfortunately, the kit is just sitting in my garage waiting for repair. No extra holes that I can see on them, but in need of cleaning, possible restaining and repair.
There was some old heads on the drums, and I did like what I heard when I first bought them. I'm sure with the right heads and tuning they will sing.
After the split of Camco, Tama sold off the rest of the shells left over, used Swingstar shells from what I've been told to use for the Camco line. Slowly realized that the pedal was the best thing they got. As far as DW goes, everyone knows that story.
The lugs that Tama/Camco used have a very similiar look to the original Camcos, and I don't think that was a mistake. Brilliant marketing, until DW caught wind. The shells that you have in the picture look like the same as mine, quality product, enjoy them.
