Having never even seen an old K I have had a stroke of luck recently. Bidded on an old fashioned auctioneers website and scored dirt cheap a nice old 70s Premier Royale drum kit which i noticed came with a whole bunch of cymbals, a camco pedal, and masses of old stands (in a pretty rough state tbh). Anyway nestled amongst the cymbals was a 13.5" K. I think it's 1960s?
Having struck gold once I also bid again on what was incorrectly labeled an old A Zildjian, it's actually a really nice 12" paper thin K. I can't work out a date on this one though as some of the stamp has gone. anyone more the wiser?
The hi hat sounds great, i've paired it up with the bottom of the reissue A Zildjian and Cie.
