Vintage Baseball Glove/Mitt: (1960's) USA made Seco Sports Equipment Corp. SE 315 (private label - possibly manufactured by MacGregor) "Big 6" six finger measures 8½"x 8½" (an 11" pattern) and is endorsed by Mike McCormick, 1956 - '71 (block letter endorsement in pocket). The photos pretty much describe the glove’s condition and features. As for what you can’t see or might not notice: Uniformly padded leather feels smooth and flexible. No holes, rips, or tears inside or out; shows normal wear. Leather lining also smooth and comfortable. All lacing original. Rolled leather piping in good condition; stitching and seams also. Easy-to-read stampings. A previous owner printed his name under wrist strap (you have to look for it to find it). Nice 60's glove displays well, feels good to wear, and is enjoyable to use. Has been cleaned and conditioned.
