Hi, I am reading old Twang catalogs and Japanese Domestic Stratocasters specs. I noticed that ST62-53 (or ST57-53 and ST54-53) had Japanese Alnico Pickups with staggered poles, called ST-Vintage. But in 1994 and 1995 catalogs these strats were were equipped with ST-single pickups (made in Japan, too). Searching ST62-53s pictures, I notice that this guitars usually had staggered poles pickups, like previous ST62-55 and ST-500 models with ST-Vintage pickups. But I also noticed that few STxx-53s had flat poles pickups. Is it possible that these flat poles were aftermarket pickups or ST-Vintage and ST-Single are not the same model? Maybe ST-Single were ceramic with flat poles?
