Engine in the u- control plane looks to be a Rocket .46 ignition, next to the left a Arden .099 or .19 with a clear plastic tank ,next I can't find ,to the left of the shelf post is a Bantam .19 ,next a Rogers .29. & the next one is a Ohlsson & Rice .60 or a .23 . The rest are too tough for my old eyes & memory but I have had them all at one time & all are ignition. Now I would say 1946 to 1950 . Max H.
