Rats nest, might be lumenition if the metal box is kind of cast and finned send it to me for "environmental disposal"
could be Velleman kit as it sounds distinctly DIY if it is its a rather good thing to have doing away with the increasingly crap condensor
boyer comes in a plastic potting box and has a green and a red led on top
all of them should work fine on a standard coil once the wiring has been tidied up
( +ve wire to coil may have a split i make up piggy back jumper this powers the black box. second wire to coil from the box - that's the switching low tension circuit now replacing the points , then there should be an earth, and finally a trigger wire that goes to the original points wire that dissapears down the cowling)
