I can't find any info on re-rings on early APKs and they never had them later, from the high-tension lug period. Again, I'm assuming they are birch and probably with a sandwich of meranti. The APK/XPK line has had several shell compositions, most of which had inner plies of asian woods.
Paiste cymbals from the 70's almost all had black logos, i think the blue-label 602s being the exception. That makes it al little hard to recognize a model from these pics (if the cymbals were purchased around the time of the kit). Wish I could help more, but info on these early APKs seemed limited. I'm also wondering if there were also different model names for the North American market. Maybe they didn,t want to market the name Royal in the US?
