  • is over the really fllimsy battery connection which of course is bent away so no longer making contact. So feeble that there is no point in bending back although for illustrative purposes I have for the pic) as it will soon bend back or fracture. At the moment I'm thinking of cutting a bit from phosphor bronze shim and rivet/soldering with an eyelet+tiny washer through that hole marked with an R and doubling up the existing. Not possible to sensibly remove this hinged brass as the pintle is rivetted in by the look of it.

Worked very well, almost looks as manufactured. Small phosphor bronze strip from a small limit switch ex-CD traverse, cut down and bent. A matrix board "rivet" vaguely crimped over , then soldered to the original. around that hole , excess solder and rivet pin cut away, and a bit of the plastic cover milled away , to slide over the rivet head and solder blob.
