HalfaDouble,
If it has one( some become lost) the adjustment screw would be between the triggers, they are sometimes hard to see in photos. I understand the confusion because of having 2 barrels and 2 triggers with only I striker. On the other hand it would also be confusing to have a selector if there were two strikers.
