Guillow's put out a Mark-2 version of the Barnstormer that did have flaps. I think I have one in my kit collection. As far as I remember it is the same airplane, but flaps added once that feature became popular on c/l stunt models. Not sure what the date is on the kit, but maybe this model could have been built from the Mark-2 kit? Flaps obviously could have been added anywhere along it's history.
If you can put up photos of the other unidentified airplanes and we can take a crack at them. That's always fun!
Type at you later,
