Hi Cowboy, Mike, JD and Joe,
The web styles of the fielder's gloves seem to help identify the different years that a glove may have come into being. While certain webs on gloves may have been revisited from time to time by glove companies as the years went by, overall it seems the webs help to date the old gloves as they evolved.
Many catchers mitts and basemen's mitts have very similar web styles to the fielder's gloves and I love the look of the old fielder's gloves the most so I did my book focusing on the evolution of the Fielders gloves and their web styles in hopes people would enjoy looking at the pics and learning about the evolutionary process of the gloves.. Using a shameless plug at this time,

my book is on ebay right now and if you tell me you heard about the book on ebay I will discount it by 4.00. Being I am working towards a new book I am hoping to sell out the remaining books I have on hand, which there are not too many left in my supply. It describes and shows pictures of the various fielder's gloves and web styles up through a solid web and a string laced between the fingers that came into being in the late 40's early 50's. It also has great glove pics that were shared by Jim Daniel(ebbets55 on this thread) and Rob Mucha(Glove Crazy) and to top it off Joe Phillips (softball66 (who writes the Glove Collector Newletter for the hobby) reviewed the guide. Wonderful guys.
There are some great glovers on this forum and they hold a wealth of info about the hobby. I have put my energy into the book and want to continue a bit further with this next book. It took more hours than I ever expected and the Guys certainly spent their time and efforts to hammer out the book and my printer does not print for free, but I have had glovers and non-glovers who have told me they enjoy the book and I am hoping it will even promote the hobby a bit further. Might be worth checking out.
I have ran across a glove that Joe Phillips has been helping me to identify and it looks like a "fielders mitt" I will try and figure out how to get some pics of it on our thread. I think I got very lucky in finding this one and will share the pics with the group..
JD, Joe believes it to be a fielder's Mitt from 1910.
