Mike, I agree with Al, the pictures are awesome.
I wish I could add information to your quest, but the only thing that I can say is that as a youngster, I recall seeing some abreviated games prior to the Yankee games at Yankees Stadium during the 1940's.
They would play two, or three innings prior to the Yank game, and the teams were made up of players from the fire dept, police dept, and sanitation dept.
Lot's of luck with your search ... It's an interesting topic.

PS
Some time in the late 1970's, I found myself in Hoboken.
I said to myself, "Let me check out Elysium Field" where the Knickerbockers use to play.
Believe it, or not ... I found the spot, and to my disappointment, that's exactly what it was.
I found a building with a plaque on it ... stating that this was the spot of home plate, where the Knickerbockers played their games in the 1840's.
