U-320 3/8" roller bearing drill. Have it set up on a mini drill press. Beat up, but still runs perfectly. Searched for one in International Tool Catalog, but could not find it. Late 50s, early 60s style. Does not show up in the price lists... but I did not look at *every* catalog. :)
Found some Kraeuter lineman pliers without a model number and with the early handle pattern.
All the ones I find images of, have the model number. Earlier than model numbers? 8.25 inch.
