Nice authentic BR setup. However, don't think it was stated (perhaps implied) that they were used by the man himself. The kit is a Fullerton era set and at the time it was manufactured, BR was no longer associated with CBS and Rogers.
Is it worth the money? Hard to say. Even though the dyna is a FUllerton era drum, it would still bring a bundle by itself. Add in a factory correct 24" bass drum with the BR hardware configuration, the toms, and correct hardware, and you have a pricey kit. You don't see an original set up like that too often, regardless of era.
The listing did not imply that BR played or owned this kit. The point I made is that they are overpriced for what they are. The drums are a very nice kit. The Dynasonic is a real gem for folks who like Dynasonics. Personally, I found them to be more problematic (finicky) than I wanted to deal with. And, I not only played Rogers, I sold them, too. I began as a manusacturer's rep for Fender when the company was known as Fender/Rogers/Rhodes. So, I sold a ton of them.
Just realized that the statement in blue reminded me of the Sy Sperling Hair Club For Men commercials.
Additional thought: No knock against the Fullerton production intended....But, the Ohio made Rogers drums command significantly higher prices on the vintage market.
Donn isn't shy about asking top dollar for the good stuff. But I don't know that he expects to sell them on eBay for this kind of coin - it's a cheap advertising vehicle, and he can always make an off-line deal if somebody is really interested...
