I found a couple of Slingerland drums that were the same vintage and color as my sons 67 Ludwigs. The wrap is identical, Slingerland and Ludwig must have bought their finish from the same vendor. I mean it's identical. My son doesn't care, unless you look at the lugs you cant tell.
Yes,they both got their finishes from a company in Italy,who's name escapes me at the moment!
