There is a picture at http://www.hippodromebristol.co.uk/Sydney%20Phasey.html with this caption:

"Comedy and dance duo Morris and Cowley (actually, brothers Harry and Frank Birkenhead, who took their stage names from the Morris Cowley car), used to perform as old soldiers, or as cricketers racing across stage. They appeared 13 times [at the Bristol Hippodrome] from 1926 to 1967, latterly in nostalgia weeks."
