That's exactly what I expected, Ross.

In the meantime I've removed and opened up the starter. It is a Delco Remy unit. I cleaned everything up, at first glance nothing seems to be wrong with it. After all the motor was functional just a bit sluggish.

The thing is that the commutator needs redressing a bit, nothing serious, no deep grooves. The other thing is that the mica between the copper bars needs undercutting. Funny that you read on various places on the internet never to undercut the mica on a starter motor because of the copper-carbon brushes. They would wear rapidly and fill the spaces between the bars thus causing a short. Urban legend????

On the other hand the Packard manual suggest undercutting to 0.030. I guess it is wise to follow the manufacturer's instructions, don't you?
