ive got a heap of acros, but i too have a 67! 67 was the first catalog that an acrolite was shown as a part of a kit,that i recall. it had been shown in a few prior catalogs as a stand alone snare drum. clubdates had previously been shown in the 60's catalogs with jazz festivals,then pioneers in 64, and with the acrolite in 67. maybe this increased the production of acrolites in 67,as it appears many of us own one...
