Technical Mallory distributor

Going through some old boxes found this distributor. Model z type 11A. Any information would help. Thanks View attachment 4911363

The 11 stamped on it tells us it is for Model A and B Ford, and the Z means it has a vacuum brake. The fitting on the side can be connected to manifold vacuum to control the advance but the leather pad inside the vacuum brake housing is probably hard as a rock and ineffective. You might be able to make a replacement, or try to contact tubman here on the HAMB he may have them.
If the rotor is p/n 24215 it has a spring loaded contact and I believe you will need the old style 24004 brown cap. I had a 324 Olds Mallory and the 24215 rotor made contact with the later 4004 black cap preventing rotation.

 

Okay thanks rotor #4215

Your 4215 rotor is perfect for the 4004 cap. The early brown cap commands more $$.

 

There’s no points inside. Looks like setup for dual

I thought that the Z in Mallory coding referred to "centrifugal and vacuum advance" rather than vacuum brake. Y for centrifugal advance only. I could be wrong though.

What do you think it might need other than cleaning, points and the leather piece for the vacuum brake?
BTW, as old as it is it may use 24205 points, or maybe the later 24875's.

 

I make the leather piece for the vacuum brake from the proper 12 oz .leather (which is about 1/4" thick) Unfortunately, I am in Florida for the winter and my shop is in Minnesota. If you can wait until next April, I'll send you one if you remind me then.

 

I have a vehicle with a Mallory distributor that I cannot find anything on. It's not even on the list above.
It's a model ZA, Type 20A. No serial number stamped on it.
