Help Identifying Vintage Motorcycle Frame G4 / 571 and Gearbox
« on: February 01, 2021, 03:44:45 AM »
Hello. Just seeking advise please on helping to identify a vintage motorcycle frame Im guessing from the 1920s or 1930s.  Has frame number G4 / 571 or GA / 571 stamped on front tube just below steering tube.  Possibly Excelsior or Sun ?  Please see photos.  Bike has a Villers 250 cc 16A motor and thanks for advice to date.

Also attached is photos of gearbox on bike which I am trying to identify. The box has a ‘G’ at the bottom and number PB 978 or P13978 but no brand name. Can anyone tell please what model / year / brand gearbox it is.  Thanks

Excelsior. G for 1937 and 4 for Model 4, and the 571 is the actual frame number.

It should have a Burman box.
