There they are! Exact match. Thought it would take me longer for find them. Magnum XM71 Series. This was actually the only reference to them I could find anywhere on the web.
There are actually great drums but they need some attention and refactoring to get them to their potential.

John,
I owned and worked a XM71 kit (black) from 85 to 92, while play with No Boundries (progressive jazz one, not the country one!). Ran a set of 6-8-10 Roto’s off the left, with a upper half set of Octo’s above them. Add a bunch more brass, and this was a monster an totally inclosed work horse. I sold the kit to John Yaney in 93. I downsized do to smaller venues, which limited the riser space, and this kit was very “Thunderous” for small clubs. Great for large halls, etc.
I too, have been looking for a replacement information, and have only found the same “one and only” info.
Drop me a line, and I can keep you posted as the search continues.
