I never really think about "upcycling" but I have an oil gauge from the primary school I went to , it's been kicking around for a while so maybe a clock?
And where is best to get the gubbins?
got a more than a few of these cheap quartz battery chinenesium workings kicking around, drop me a pm with an address and I'll stick a couple in the post to you..
Nice BUT. I think that they are loosing the original purpose bit, I would be tempted to fit the battery unit (I have done a few similar) Fit slightly shorter pointers and re-number inside the existing markings,
