Well I have both good and bad news, the bad news is only 1 of the 2 boxes arrived. I'm nervous as hell about this, contacted the seller and waiting for a reply and I called DHL and they said only 1 box was scheduled to be delivered. Hopefully it will be resolved soon otherwise I'll freak out.
On to the good news: the bass drum and 13" rack tom came in good order.
All hardware is indeed Star era: the spurs, claws, t-rods, tom mounts and brackets, even floortom legs. The badge is quite unique as well as it doesn't state any series. The shells are all painted grey inside like Star drums were at some point, and no rerings. So a theory would be that this came from the Star Royal series and would be made into Tama Royalstar.
Overall the drums needs some TLC, some rusted parts here and there, the wrap on the bas drum is cracked at several places, pitting on the lugs. I'll take the time to bring this kit back to life and hopefully the other box surfaces soon. In the picture you can see the badge, the tom mount and a weird holder of something. I don't know if it's for a cymbal mount or and percussion item. I'll look into it in the Star catalogs but if someone has a clue please let me know. More pictures will follow as I'm not feeling to well right now. Cheers guys
