I have the '71 Ludwig and '63 Slingerland sharing a room now, and I'm collecting more hardware for the Ludwig, rather than poach hardware off the Slingerland.
To start, VintageDrumBug also had a 70s Ludwig Atlas stand so I bought it when I bought the set. I don't like putting the weight of the toms on my bass, and the 70s Atlas and Hercules stands used the same 1" diameter as the tom mount. So voila, I have my toms off the bass, and a cymbal mount for my Z-bell.
I found a 70s Hercules snare stand at a local pawn shop. Yes, that's a DW snare on the set (for now, anyway.) I like wood snares over metal, but I'm considering an Acrolite or Supraphonic.
The rest of hardware though, is current generation Ludwig Atlas. And I have to admit, Ludwig hardware is better than I expected. I bought the "standard" hi-hat stand and boom cymbal stand, and the "pro" Atlas pedal, and I'm very pleased! They're easily as good as the DW hardware I use on my other sets.
The bass drum head is from vintagelogos.com. The cat logo is probably silly for a man in his 50s, but my granddaughter thinks it's cute.
Now I need vintage Zildjian cymbals... and the search continues!
