Found no new photos, but potential dimensions info: LF 250, CF 440, RF 255.
South End Grounds II (1888-1894)

Dimensions: "The dimensions of the outfield were 250 feet from home base in left field, 445 feet in left center, 500 feet to straight away center field, 440 feet in right center and 255 feet in right field."
I'll cover the Cubs a little later.
