I will put my vote in for 1959 WMS Golden Bells,
as it is both relatively common and affordable for a woodrail,
and has pretty good rule set and is fun to play and nudge away at.
I got my first one for about $200 at an early PAGG show
in the mid 90s from Jim Tolbert.

Found my 2nd one about 10yrs later at a Salvation Army thrift store
in Orange County for $300.
Interesting thing about my SA Golden Bells;
is that it has retrofit stainless steel side rails,
to give it a more modern look (probably by some Operator in early 60s)
when everyone went from woodies to S/S siderails on pins.
Not a good look IMHO.

That NAGS would be the one that i would be after.
