Mallory Distributor ID help

At the Portland Ind. gas engine meet today I got a N.O.S. Mallory dis. for 5 bucks. Its a model YL11A, which I think is for a Ford banger. Can anyone tell me for sure?

 

without going back out to the shop to look at ones i got ,pretty sure your right. good score

 

Yes, it's for all '28-'34 Ford fours.

 

Thanks for the info guys. I was thinking that the 11 meant banger but was not sure. Illl put it in my 28 this weekend.
