They appear to be Swingstars,or Royalstars 80's vintage and in either case not worth the asking price.
That's right!! BUY them... and then burn them, or they can be used as water buckets to wash the car...except the floor tom...Vintage Saw Dust?? Their worth nothing other than rims, lugs, legs etc. and those are the cheapest junk at that time. Sometimes theres instruments that need to be destroyed like a damaged flag. Burn em!!! Doc
