Welcome! Your drums are wonderful. I would love to hear some of the stories behind them. Do you have any recordings of Dad gettin' busy?Anyway, to the drums~what you have are indeed a Japanese "stencil" brand. These stencils are all identical kits, from the same factory, but have something like 100+ "brand names" owned by various American and European distributors. They would actually compete against themselves in the same town, at every music store by offering "exclusive territories" to each of the stores. Say I am the rep and you own Fred's Drums. I sell you Apollo and give you the territory of 25 miles. I go 3 blocks down the street and offer Joe's Music a territory on Stewart drums, knowing they are the exact same drums, but you and Joe don't really know that. I get paid no matter where the brat decides to buys his drums. Cool way to tie up the market, eh? These are from Star, the company we know today as TAMA. Your wrap is called Red Agate Pearl. These drums, from Star, were typically modeled after Slingerland, however yours are modeled after Sonors' teardrop lugs on the bass, and Slingerland Sound Kings on the toms and bass. This is the first time I have seen this, a mixed set of lugs from the factory. But it is an 8 lug snare, so maybe that is why they used the teardrop style on the snare. Many people today, unscrupulous ebay sellers, take these and strip the parts and sell them to unsuspecting buyers as the real deal. The lugs are almost identical and many people who are not really well versed in parts buy them and either never know or end up in a fight with the bad sellers. I would love to see close up pix of certain parts. The strainer on the snare, the interior of the bass or snare, and close up of the bass lugs and T-rods. This will give us the era, unless your dad remembers when he bought them. These old drums have a sound all their own, and we have developed some preservation techniques that also help "clean up" the tone and make them actually playable in public venues in today's world where everything is mic'd and tweaked.Those are some sweet drums. I would like those pix as I am using all of the early MIJ stencils for research and every kit I can get info on makes my life easier, and when they are linear, from one family member to another, it makes the research that much easier because there is no guessing as to provenance. Another member and I are collaborating on the possibility of writing something on the lines of the books on Ludwig, Slingerland, Rogers and Gretsch. Anyway, cool drums, you should like playing them and if you would like, I can give you some pointers on how to deep clean and restore/preserve these wonderful old drums.
