Mallory Dual Point Distributor

I was wondering which model Mallory Dual Point Distributor is the correct one to use on the 226 Flathead Ford? Are there more than one that can be used or which one should I be looking for?

Thanks

I have a model 7CM which fits a 223. Don't know if this helps with your quest or not, & I don't know if it would work with your application. The 223 is the second generation OHV after the 215.
