I made this tool many years ago when I was running and building Spalding Flamethrower ignitions for custom applications. The tool itself probably dates to the 50's and I modified it to ***emble/dis***emble the distributors. The standard nut driver end removes the acorn nuts from the cap...the other side has a custom made driver which slides down over the studs and facilitates the removal and replacement of the unique spanner type fasteners which hold the ***embly together. Hard to describe but if you ever messed with one of these you know what I'm talking about and you went looking for a tool like this. Thought maybe somebody could put it back in use. (I was going to make a 2nd tool and never got around to it so I'm including the extra handle for free ! ) $25 shipped to the lower 48....Paypal only please.
