Help with early Singer

[vac-o-matic]

Can anyone tell me the approximate production date on an A1 Singer straight suction upright? My guess is late 20's-early 30's?

A-1 Singer was the sleeve bearing model. 1928. Made by Steurtavant for Singer (private labeled) - as was the ball bearing model A-2, which launched in 1930. Stan Kann had both and showed them off all the time.

Thanks for the info!
