All this speedo action of late, I really should consider changing the name of this ol' Blogaroony!
Following my plea the other week looking for one of these, Chris left a comment saying that he had one that he took off an early Bantam. After searchin' through the accumulated shed detritus he's finally found it, and here it is, just what the doctor ordered. I've spoken to the guy who rebuilds 'em and it's not a problem to fit an 85MPH dial to it (although the red numbers on a grey face is no longer available.) and re-calibrate it to suit a Trumpet gearbox drive. The bodies on these are alloy so it will polish up quite nicely thank you!
