The three cross bolt guns make an interesting story by themselves. The one shown with the Brad Batchelder restored gun must be a non-selector single trigger (which I did not know existed) as there is no way to return the selector pin to the right side.

One of the other two must be a conversion from single trigger back to double, but the slector pin is still in place. Note the factory checkering pattern with the border around the selector (a recent LACA newsletter showed the opposite - what must have been a conversion from double to single with the cut out recess running into the checkering).

All three guns seem to be on the trigger plate action. I thought less than half the guns were on that action,so that is a bit odd, but with only three examples, really does not prove anything.

Super display; thanks for sharing it with us!
