Cardiff City Football Jerseys

Are there any kit experts on here?

I came across this photo of the Cardiff City players involved in a Public Trial match prior to the 1919-20 season. Lots of familar faces, Fred Keenor didn't play as he's wearing a suit.

The first team probably wore the regular blue jerseys but what kit did the second team used. The jerseys seem to have a different colour across the shoulders compared to the rest of the jersey - perhaps blue on white?

Does any know?

Wow. Never seen or heard of that kit. I suppose they must have had away strips even back then.
