The Stanley 803.

When I have a tool that breaks, I am fortunate enough to be able to go into my Dad's shed where all his tools are still stored, to look for a replacement. My Hand drill recently broke and I found this old drill in Dad's shed, with a little cleaning and lubricating it works well. As far as I can see, it is a Stanley 803, which was made between 1956 and 1994. I suspect this particular one was manufactured in the late 1950's.
