I'm skeptical about the claim that this fellow was a scout. There is a database of scouts on the Hall of Fame website at the following URL, and he is not listed among the Howards:
Search | Diamond Mines
I'm communicating with the person in charge of the database to see if part-time scouts are omitted from the database. I'll post again when I get an answer.
If you use that database to check players, you'll see that the scout who signed Ken Oberkfell, for example, was Steve Vrablik, not Gary Howard. Perhaps Gary helped in some way, but I don't see any evidence that he was actually a scout.
Similarly, as to his being a player. If he had been in the minor leagues, it is likely that he would have been in the baseball-reference.com minor league database, and I don't find him there.
I began a newspaper search on Gary Howard and baseball, but it is such a common name that it simply resulted in hundreds of hits, and I just don't have enough to go on here.
