Ross,I have a unfired Liberty 45/70,looked a loooong time before I found one.During that period I ran across two 300V's, one I passed on the other I have.Wood was the deciding factor.
As for Clayton's book,that was printed in 1983,I'm sure things have changed as it seems everything is getting harder to find.Seems a lot of the older guns are in hands of people who have them for what they are,not for what they are worth as far as collectability.I have a friend that has a pre-prefix 222 that he bought new,will never let it go and it looks as if it were used as a club.He is a farmer so you can go figure. :roll:
