I see parts of a Blue Note setup and what I would assume was a Downbeat 20" bass drum. The kit doesn't appear to go together based on the sizes, but then again they have this listed as a '66 and there is no catalog in the guide pages for '66, only '67 which i didn't think differed much. I guess if all the serial numbers are close, or the date stamps are identical, or the chance that this kit was ordered custom back then.... I don't know. I just have a hard time thinking this was a stock kit. What do you guys think?
