Fantastic! I thought I wouldn't ever find Revolvers for my Tioga build (my Richter 8.0) but someone got in touch on here to say they had a tatty pair. I've cleaned up the BB and have the arms powdercoated, but I haven't fitted them yet. I was waiting to find the correct size Tioga seatpost, but now that's fitted, so no excuses.

Thanks! I spend a lot of my free time staring and thinking about my bikes, trying to envision what they could look like. It's nice to actually make them real.
Thank you! I'm lucky to have found a proper matching fork. Maybe in a few years, I'll upgrade to a black and orange decal RS-1, but for now, this Tange is great.

Disassembled, cleaned, and sorted. I could not get the drive side cup out of the frame, it is fully seized in there. I still haven't tried heat yet, but that will come later. Even if I get it out, it will only be kept as a spare. I picked up a NOS Tioga Revolver BB cup set on eBay, as well as some new SS6903-2RS bearings from Japan.
I'm also talking with a friend of mine who has a lathe and some tube/bar stock, and he's going to work with me to recreate the collar, spacers, and the setting bolt washer. I'll ask for spares, and I suggested he make them available for sale as well. If he agrees, I'll post details here.
Does anyone have a lead on preproduction decals/transfers, or even a paint mask, for these? I've seen the question asked a few times, but never answered. I haven't asked Gil yet.

No, but I'd also be interested if you find some.
For the last drive side BB I couldn't get out with my normal big wrench/spanner, I bought the wrench with the cut out to fit over it exactly, then used a big bolt and washers to hold it tight to the cup. And then, after lots of penetrating fluid, a length of heavy hardwood to deliver dead weight blows to the end of the wrench. When it starts moving, more fluid and back and forth hammering. It came out ok without damage to cup, frame or tool. (I always have to remind myself to loosen it in a clockwise direction.)

Yep, the one I need is a Park Tools HCW-4, and I'm also going to look for a BBT-7 for future lock ring adjustments. I don't want to tear up the metal like the last guy did when he installed these.

I fitted these tonight, in time for my weekly group ride on Friday night. The NOS cups and new bearings arrived, and were installed within the hour! 
Needless to say, I was eager to get these on the bike, and I love how they look. They are so easy to adjust, and I can take the cranks off in less than a minute, so chainring swaps, and the inevitable repaint will be nearly effortless.
I noticed that the previous guy used an unnecessary 1.25 and 2.5mm spacer in the stack, so his cranks were not installed properly. Nice that I have them though, since I can now get them reproduced, along with the missing setting bolt washer.
Since I don't have a BBT-7 for the proper Revolver lock ring adjustment, I decided to use the one from the Tioga fully adjustable bottom bracket that I removed. They are nearly identical, except the Revolver one is smaller in diameter by a few millimeters. This makes all the difference when using a standard Park Tools HCW-5. Also, the water sheath from the old Tioga BB is identical to the one from the Revolver, in case you can't source one easily.
Lastly, here is a clean scan of the parts list, without annotations, curtesy of holden.
