Hi,
I've an ex-museum(!) two-tone green '54 A7SS, with a '55 head.
Bit of a bitsa: plunger seat, wrong tank badges and knee grips, wrong rear shocks - too short, v poor front brake with green linings, forks poorly installed with different length springs and knackered circlips (one being a piston ring!), monobloc carb, '70's headlamp inner, magnetic copy speedo wildly inaccurate.
Looks like PO tried to fit rear sets and gave up.
But its the only bike I've had that's actually made me laugh riding it - such fun.
bought to ride but has turned into a project.
Andy
