Hi ye'all

Can anyone tell me how good are Proto Tools from Ingersoll-Rand? I just
inherited a bunch of tools of this brand from my father. I did a little
research an know that in 1984 Proto Tools was sold to Stanley and are
suppose to be the best industrial hand tools in America. But that is
now, what about when Ingersoll-Rand made them.

Also, is there a way to determine their value today? I wouldn't mind
cataloging them with their market value for insurance purposes.

Thanks!

Rose
