What Crab distributor do I have here?

[4tfred]

From having collected spare parts here & there from old junker motors, i am in the process of cleaning up and getting rid of some items.
So, can you help to identify what year this distributor is?

At the top is a "3"--at the bottom is 35513. Near the bottom bolt hole is stamped "LOMAC"

The main shaft appears to be tight.

What might be a fair value of this item?

Thank you, Fred
