I don't understand how it's possible for anyone to rebuild the two
player actions in each example in this list in the same amount of time:

- A double-valve Standard Pneumatic Co. player action with 50 stripped
screw holes in the gasketed red gum parts, stuffed with toothpicks and
oversize screws that cracked the wood 40 years ago, vs. a single-valve
Standard action with all good screw holes;

- Any player with sustain and split hammer rail pneumatics vs. the
same brand with all manual control levers;

- Glued-up Gulbransen stack with a delaminated plywood trunk board
vs. a pristine Aeolian stack;

- Cecilian stack with rusty valve canisters in the same time as a
2-tier Seeburg stack;

- For that matter, an early 4-tier Seeburg stack vs. a later 2-tier
Seeburg stack.

If it's supposed to take a set amount of time to restore the first
examples in each pair above, then how can it possibly take that long
to do the easier one of each pair?
