Ah the memories this conjures up!
Bholl actually gives us a good advertisement to draw from. Given the small numbers of manufacturers, one could assume that the better dress shoe manufacturers made golf shoes as well; hence J&M and FootJoy. I'm sure we could imagine the line of Classics as the early models, with leather soles and a variety of wing tips and cap toe styles.
Since golf was a more affluent game, people would only buy better grade items, so shoes of this type were the choice I'm sure.
Not sure about you, but I'd love to hear if FJ has a few snaps in their "hall of fame" museum up there.
