This area too is one of my favorites in that we can see (thanks to vintage photos and the timing is right) what the players were wearing.
1. I had the opportunity to see purported game gloves of "Lefty" Grove and Billy Southworth that were up for auction. I knew immediately what to look for in Grove's model because I had a couple of Reach ads on Grove with the Vance- type lacing Reach glove. (He had given the glove to his yard man in payment). The Southworth glove was claimed by family member to be a Bill Doak glove. Only, it wasn't, it was a Rawlings Southworth Model with the adjustable web (holes in the web where you could secure it tighter or looser. Best image comparison, in color, I ever saw was on a Grove glove sold by Hunt's, with an almost perfectly matching picture to glove.
Best shot on the Rainey trap is the great artwork closeup of Ival "Goody" Goodman reaching to the heavens for a fly ball with the Rainey most prominent in the painting.
I sent a copy of this to Stockbuddy for his displays of his Rainey webs.
On the Averill glove I cannot determine if we're seeing (a. lacings only, or: ( b. tunnels with out seam sewing. Now there were a number of cross hatch laced gloves used in the 1930s and recall having a "Red" Lucas where it appeared there was never any tunnels used.
Cutting a hole in the glove seemed to be a "catchy" theme among infielders of the 1930s: Durocher, Bartell, Herman and I'm sure many others were following the old Wagner-Maranville-Wallace tradition of removing the outer leather for a better "feel" of the ball.
Another you will notice in the late 1930s photos are that players would use white bandage tape to wrap around their two-tunnel gloves, creating a larger and solid pocket and this may have led to the full or barrel web coming out in the very early 1940s.
Yes, if you have that Conlon set of black & white photo card, go through it and take in the glove pictures.
Still, one of my favorites is the shot we ran in the newsletter of Lefty Gomez glove that appeared to have on finger tunnels from the back, like the glove was encased like a base mitt, it was a two or three-finger style. Many of you will recall it.
