I think this is a supressor ! I guess these were fitted to wd motorcycles HT leads so they don't interfere with radio sets and so on !
are they any good ? Iv had them fitted to 30's cars and they are of no use what so ever they made the cars miss and splutter so i took them off
here is a picture , if anyone is interested in one i can get others %%htmlItem_1%%
I had one drilled with a 7 mm drill and put the HT lead through it to make it look original. It's not really a good idea to use in with a magneto ignition.
