While looking for a starter for my Ford flathead, I found this.

That would make a good replacement but it is only available in 12 volt .
I notice they also sell and service these. Magnetos (//http://www.autoelec.com/html/wico_xh_1113.html)
I bought one of these starters for my HG68 that is powered by an 1XK3 Hercules.
The nos starter is a little pricy but the one from Automotive Electric Services is well worth the money & turns the Hercules over like there's no tomorrow. I'm very pleased w/ the starters performance and costs..
I ordered it on a Monday & UPS delivered it on Thursday.
