We have ads showing the engraved Ben Hur in 1936, 1937, and 1939 (in root record). We have no ads for an engraved Calhoun period. I may assume there was an engraved Calhoun, but for now, I'm not voting based on this assumption. This watch doens't need a mount for me to confirm three ticks as a Ben Hur. If it were displayed mounted on the rubber band which came on the Sunday morning newspaper, I would still give three ticks confirmed for Ben Hur.
