We have a clear blue vistalite here that is in wicked shape! The seams are good, and the bearing edges have held up quite well, and there is very little wear and tear from the years.
The kit has been pieced-marked together, so the serial numbers do NOT match up.
I’ve replaced the floor tom legs and the heads, and I have replaced one of the rack tom’s imperial lugs with the Atlas drum mount bracket. That makes mounting MUCH easier and the drum resonates a LOT better than it did with the originally installed mount. Also I have removed all of the original muffler devices because they were more hassle then helpful.
