This group was formed in 1923, by some former members of the Pender Troupe who had stayed in America after Bob Pender returned to Britain. As well as Archie and Tommy Lomas, the troupe included Doris Pender and John Lomas, together with several American recruits. They did a Pender style act, toured the US and Canada, and split up in 1925.

I found a caricature featuring the Lomas Troupe:-
