What is the "nub" on the water pump that is circled on the attached picture? Is it a grease point?

yes it is, but replacement leakless style pumps have a sealed rear bearing which is non grease able and a dummy fitting
 
Yes, for the rear bushing. I use water water soluble grease on that one so if it happens to leak into the water system it will not turn into globules that clog the tubes.
 
The original cap could be removed and the Ford grease gun (with it's now unusual cone fitting) would fit the cone underneath. Later versions of these designed for the aftermarket have the more common ball top grease zerk fitting.

The brass cap should be replaced - although a modern grease zerk might work as a check valve to prevent water from issuing from the hole.

Shouldn't do more than one small squirt perhaps yearly, or monthly if driven daily.

Thanks everyone for your information. These Model A's are amazing, learning something new about my car every day.
 
When I bought Vermin, my Avatar car, the seller discounted the car $250.00 because the stock rebuilt waterpump was dripping. Someone had put a modern zerk fitting without a check ball in the rear of the pump! (DRIP, DRIP, DRIP!) No, that's not my signature! Bill W.
