No, this is a divers helmet distributor. And it doesn't take much force at all to bend it when all the parts are stripped off. I chucked the small end in a lathe and measured 0.060" runout at the journal on the other end. It only took a few taps with a soft hammer to get it straight to within 0.002". It's pretty spindly in the middle as you can see but I was surprised how easy it was to straighten. I cleaned the shaft up thinking maybe it was cracked but I couldn't see any.

Some rough handling would have bent it easily.

I bet the last person to set the points must have struggled.
