Hi Dave, IMO, as far as the hardware is concerned, and if the set was mine, I would at least like to have the proper BD Rail Consolette, the proper BD Cymbal L-Arm, and the correct BD Spurs-FL Tom Legs.
In other words, at lease trying to keep the main set itself intact, and free of extra holes, or other oddball hardware in this regard.
Other than that, there's not a real helluva lot of importance of having the correct time period Cymbal Stands, Hi-Hat Stands, or BD Pedal, in which much of this was not of the quality of what's made today.
For these, I would recommend a DW BD Pedal (5000, or even better yet, the 9000), DW Hi-Hat Stand, DW Snare Stand, and DW does make vintage style flat base cymbal stands, that should work wonderfully, and look mighty nice with your vintage set. If you have a good Drum Store, or a Guitar Center nearby, all of this could be gotten in one shot. In, and out, and you'd be up, and running. About the only downside with some of the DW HArdware, although it is built like a tank, some of it is a bit on the heavy side.
If you would eventually like them, then yes, the vintage, time correct hardware could be acquired at a later time, piece by piece.
As far as vintage, time correct cymbals go, the early Paiste cymbals, typically what was offered with many Ludwig Drums back then were sort of dogs IMO, and many I sampled back then were bland, and lackluster.
While the 60's Zildjians were a much better cymbal IMO during this time period, there were also quite a few dogs with these also.
I can remember going through literally 100's of Zildjian Cymbals back in the 60's at Frank's Drum Shop/Chicago to find a suitable candidate. Quite a few of them sounded like garbage can lids back then, and many new Zildjians-Sabians in my opinion do now. The exception to that usually, are the Zildjian New Beat Hi-Hats. These I personally still like better than other manufacturer's Hi-Hat Cymbals.
Whatever Cymbals you do decide on, I highly recommend trying/sampling in person. Consistency I've found is usually very good with modern Paiste Signature Series Cymbals. While in the old days, I owned all A.Zildjian, I now use all modern Paiste Signature.
Hope this helps, and best of luck! Mark
