I picked this up earlier this week along with a nice Bridgeport and a bunch of tooling. The prior owner had passed on and his widow was cleaning out his stuff. Both machines and the tooling are welcome additions to the shop. The number stamped on the ways of the 10EE are: "Lot No. EE13283". The prior owner's widow thought it was a late '50s machine but from what i've read, i'm guessing early to mid 40's. Can anyone help establish the date of manufacture?
