Man tell me about it ,what I have found is there is a very narrow window in which to really identify Rogers drums. I have a black 4 piece set with serial numbers and paper badges that identify them to the 1960's with the Holiday model#7624 on the inside of the bass drum which is 16x20. The expert at Rogers drums at this very site told me the bass drum had a pearl tom set-up on my Rogers bass drum which he was totally correct about. My two toms on the bass drum are 12x9 left and 13x10 right the floor tom is 14x15 and has a paper tag saying Holiday Model #107195 on the inside of the floor tom on the outside bracket that holds the floor tom leg it has etched in the bracket #K0999206. I have no idea what the tags mean or the etched # I am told that the workers at the drum factory just randomly used tags when they ran out of the right tags. This I know for sure is that the strip of wrap on the bass drum is pearl. I lost the other wrap because it fell off and was to messed up to repair. I look at old catalogs provided by Vintage Drums but I do not see a match on the site.
Good luck man I really can't help you but maybe this info will be able to move you along.
TOTALLY FRUSTRATED!Help2
