Vintage Baseball Glove/Mitt: (1922 - '48) Wilson 507 "Professional Model" no-hinge catcher’s mitt is circular in shape, measures 9½" in diameter (31" circumference), and is endorsed by Hall-of-Famer Ray Schalk, 1912 - '29 (facsimile signature on toe). Schalk’s endorsement is listed as "Very Rare" and of above average value in the Bushing/Phillips Glove Price Guide. The photos pretty much describe the mitt’s condition and features. As for what you can’t see or might not notice: Thickly padded leather feels relatively soft, smooth, firm, and inflexible - due to over-padding. There are 3 punctures on right side of heel; at first glance I thought that they were nail holes (as some people actually display their old mitts by nailing them to the wall); however, there are no exit holes on back. So, it’s a mystery to me how or why these punctures occured; but, they are there. Otherwise, leather shows overall normal wear; some chaffing. Leather lining exceptionally smooth and very comfortable. Entire mitt has been relaced. Rolled leather piping in good condition. Stitching and high, raised seams very good/excellent. Stampings are worn yet easily visible. No previous owner’s markings anywhere. Valuable, rare "thumper" displays well, is a pleasure to wear, and is an enjoyable challenge to use - requires the catcher to use two hands and is a good training tool for that purpose. FYI: Just as the Bill Doak Rawlings became the prototype for glove design from the mid 20's to 50's at which time (1957) Wilson introduced their A2000 which then became THE standard for gloves of the future, the Ray Schalk Wilson 507 established the standard in catcher mitt design when it first appeared in 1922. From '22 to 1948 the Schalk 507 remained the top-line catcher mitt in Wilson’s catalogues. Every vintage glove collection needs a Doak, an A2000, and a Ray Schalk mitt. (3 of the most innovative and influential gloves in the history of glove-making). Has been cleaned and conditioned.
