The Iron Arm Brand of glove and mitts has a really cool logo on the front. This 1930-40's Spurgeon Chandler "Knuckle-eze" model glove shows an arm holding a spear
The logo comes from an old English coat of arms. Note the armor and the same twisted rope design.
In addition to the Chandler "Iron Arm" glove, the "Knuckle-Eze" model was also stamped on some "Olympic" gloves made for Western Auto Stores. Below is a Pee Wee Reese Olympic glove box.
The Chandler and Reese gloves below look to be made by the same manufacturer. Denkert Sporting Goods would be a likely candidate. Joe's "Vintage Baseball Glove Catalog Resource Book" differentiates between the Western Auto in-house brand "Olympic" and Olympic Sporting Goods of New York.
