If your gauge is showing no pressure and than 10 lbs and than back to no pressure and didn’t do it prior to your removing the oil pan. Your asking a good question.
If it were my car I would check things out before running motor. The gauge could be defective, or you might really have a problem. It’s your call. It’s your engine.
I only say this because as I said earlier, I had a similar issue many years ago. Enjoy.

I would agree with your statement about there being some pressure, ...and I also agree with your statement that a Model-A engine does not have a pressurized system. Hence my reason for stating there is not a true pressure in the system. Thanks for clarifying that statement.
