Teflon Action Replacement

[Joseph Garrett]

The Thumper said: "On a 1974 'L", with full regulation, and with, and
without, back action replacement ?
Besides the crummy action parts, what other
problems might I anticipate an a beast of this
vintage?" 
Thumper,
Expect a really crappy set of keys, that require a whole lot of
re-engineering/repair/ etc.
