Very educational string here. Without positive proof on the fielders vs. baseman mitts. I "suspect":
1. There is less padding in the fielders mitt than in the baseman mitt. The baseman is going to take more "catches" than a fielder therefore requiring more padding
2. There are finger channels inside the fielders mitt and not in the baseman mitt. Some of the catalogs indicate this.
3. More sewn outer edges than laced edges. The adult mitts seem to be laced from the catalogs.
JD is right, best way to know is if you can read a model number on the mitt. I can look up (like I listed above) some of the model numbers for the catalogs I have. JD is likely correct also in his
assumption that most of these might be child's to mid youth size gloves.
This is a viable niche for glove collectors.
