Again thank you so much for the research and the posting of useful images.

The players in the 2 images appear to be wearing the same jackets. If Jim Viox is extreme right bottom row in the first image he appears to be dressed the same way in both images.

Neither the white caps or the vertical dark stripe down the front of the uniform was part of the uniform in either 1915 or 1916. That does not rule out Spring Training 1915 but would appear to eliminate 1916.

Ed Mensor and Ed Konetchy like Viox are not wearing the tartan like jackets in the second image. Likewise they could be seventh (Mensor) and ninth (Konetchy) from left in the bottom row in the first photo.

There are 35 people in the first image, 34 are in uniform, 13 are wearing white caps. There are 35 people in the second image, including 1 official and 1 coach, players wearing white caps are :- Watson, Wagner, Duffy, McCarthy, Fullerton, Coleman, Wait, Leonard, Daley, Kantlehner, Mamaux, Harmon and Viox (13)

Konetchy was traded from St. Louis in December 1913 and jumped to the Federal League Pittsburgh team before the start of the 1915 season.
