I am intotal agreement that the Type 11 is the best of the best. Type 10
is the same thing low knob with adjuster but two paten dates. It was
only made for two years acording to the type studies so it doesn't turn
up as often. Having said all that, with the 4 1/2 there are other things
ar play than the type. The 4 1/2 is a design that Stanly got right and
any type, properly tuned is a real eye opener as to what a metal plane
can do. I have to fess up that this is the one number where I found a
user that I like better than my Type 11's. I found a war casting with an
adjuster and the extera weight(I guess) makes it work even better.
Absolutly unbelieveable what this plane will do. Steve who is about
three quarters to his goal of at least two Type 11's in No. 3 thru No. 8
