I am somewhat new to working with planes. A few weeks back i had a thread on choosing what planes to buy, and it was suggested to look for older quality planes as an alternative to buying the expensive new ones. My question is how do you discern the quality of an older plane. I have just come across a Bailey Stanley no.4 plane that appears to be in good shape. However, I can not find when it was made. i know some of the older Bailey’s and Stanley’s go for a good buck while others don’t. As i said, this one is a no. 4, on the front by the nob it says Bailey, and on the back it says Stanley.
