For those of you who may be interested in Rogers Tower drums, Guitar Center has a red sparkle set in the Cleveland area store. The store information is here:
North Olmsted, Ohio 44070
440-777-7900
Ask for Dan in the drum department. The set is interesting in that it was manufactured with the tom mount further up the drum, and on the other side of the top left lug. More convenient than the normal location. In addition, the floor tom has knobby legs. There does not appear to be a modification in either case, but you need to check that out carefully. At least on of the knobby mounts has Allen wrench screws now, so that too should be checked to see if they used a matching thread or if the holes have been re-tappped (or stripped!). Could be they have all been changed.
Overall, it appears to be a special order set. It will need a collet on the cymbal mount, as well as a rod and tilter, or even rod with extension tilter.
Price is $799 and they will ship to you or your nearby Guitar Center free of charge. You usually have 7-day right of return. Might even be able to get a break on the price. It is listed in their website, but only comes up under used gear, not vintage gear for some reason.
Good luck if you choose to pursue it. Of course, if you obtain it, we will need a full report.
