Yes. The book of "Motorcycle" Road Tests tested a Star twin, originally 17 April 1952 - the Star Twin was the sports model of the A7.

"Now with the redesigned semi-uni construction engine", single carburettor, plunger rear suspension, 8" front brake.
And "handsome Star Twin insignia" on the panelled and lined silver tank, cycleparts black.

Same magazine tested an A7 twin for 1951, red finished tank, 7" brakes.

Looks like you click "additional options" (below) and then work on the "attach" box.

Plunger Star Twins only look to be 1950 to 1954.
Look anything like this ?

Hi there
According to Roy Bacon,s book the Star Twin was introduced in 1949 revised in 1951 and then discontinued in 1954 the plunger frame  came in in 1949 and continued until 1957 although the swinging arm frame came in in 1954 I believe the plunger frame was kept on after 1954 as it was considered better for sidecar use.
