With the aid of Joe Phillips indispensable hobby guide, the "Vintage Baseball Glove Catalog Source Book", most any old glove can be positively identified.
Rawlings introduced the "trapper" style first base mitt in the early 1940's and sold them right up through the 60's. The TM58 model was sold from 1956 to 1959. So, while this was a late-50's mitt, it probably was very close to the original 1940's design, with just a few minor tweaks being made over the years.
