Well I've got something a bit different, but then thats just me. It only cost me £5 at a boot fair a few years ago. Brand new in a battered box, with very dated instructions, and a free window sticker , proclaiming your conversion to all and sundry! What is it you ask?? its the good old ' Luminition' piggy back electronic box, sits on top of the coil, with a 'flashing light to show its working, and a switch on the side to change between electronic and std. It keeps the points, but when switched to electric, vertually all the current is bypassed, so they dont burn out. Works very well. If you ask nicely I might even take a photo (for the retro heads)
