I've been asking for a set of hand planes for Christmas - preferably old Stanley's. My girlfriend gave this to me early - so I could look it over and so she could return it if it was the wrong thing. We won't be returning this one - she done real good.
It appears to be a type 5 body and frog (c1885) with a type 6 cutting iron (c1892). And its in wonderful shape for a 120 year old tool.
