Very helpful thank you. My speedo and odometer have both stopped working on my Sunbeam S7 (with the speedo stuck at 40mph??). So I guess I’m going to have to strip it down to try and fix it...
@Mike- I have seen a Smiths speedo 120mph with no trip meter or no made in England written in back cover. Mechanism inside is magnetic and looks correct. Wonder if Smiths did make such examples with no trip with a case with just that wheel emblem with no made in england etched. Any info would be gratefully appreciated
Was this working, I have the same speedo that has stopped working I have taken it apart come to the conclusion that the magnet has lost its pulling strence
