Star is not a Pearl line, they were seperate manufacturers. Star is the company that would later become TAMA, they are not related.
The "Ringo" Hi-Hat is a Ludwig model. Many retailers would offer an upgrade hardware package from the MIJ stuff, and my son's Majestics came with the flat base equipment. All Ludwig, for the more serious player. This kit was played all over Oklahoma, Kansas and Texas by the 2nd owner, who dragged them all over, to many bars and honky tonks. He bought them from the original owner in 1970 as a complete kit. Over the years, one of the 12" toms was dropped hard and cracked the bottom edge of the tom. Rather than attempt a repair he knew not how to do, he just played it that way for the next 20+ years. He retired from the road in 2005 and passed away in 2008.
I purchased the kit from his son/grandson who had stored them willy-nilly in a nasty shed, unprotected. They had no idea what the cymbals or anything else were, nor did they care.
Anyway, as for the date, I say somewhere around 68-70 because of the wrap. They would have been a copy of a Gretsch, and maybe a Hollywood, Ludwig style. Early Hollywood sets had 2 12s. There is a member here, can't recall who it is, told in another post that he has a kit from that era with the 2-12s and I assume this was the way they intended it to be, but with a nod to Gretsch with the wrap and jazz sizes. It confuses me why the distributor would go for a look like this, mixing styles and sizes, but it is all original to the set up. Hope you get them cleaned up nicely, and don't forget, document the process.
How come no one ever drills swiss cheese style on old MIJ, and we find Ludwigs poked like a high school.....nevermind....not a good simile...
