Hate to bust your bubble but, they are just like any other '70s offering inside. Thick chunky parts, over sprung, short arbor . . . typical. I'm finishing up a pair with silver back straps and trigger guards. One was fairly straightforward, the other a tuners nightmare!! Tollerances all over the place . . . just a wreck!! Would be better to get all new parts and set it up as new! Unless you just have to have the horse, a new Uberti or Pietta would be a much better revolver. The parts in an Uberti are the finest ever made in my opinion even though the arbors are still too short. Piettas have a better fitting arbor (that just needs adjusting) but the action parts still have a way to go . . .
Most tuners today won't work on older guns, used guns (including 2nd gens) and lately, I can see why!!
Good luck,
Mike
