Maybe an ex-RAF aircraft that may have been `tried` as a tanker.Doesn`t appear to have props fitted.The other a/c wingtip visible maybe another `Allsoggy`,but the engine cowling looks more `radial` than a Dart..maybe a C-119....
I have been in t`123` when night-stopping in Boise,as the hotel was just across the road..however,I don`t recall getting into it via the steps outside,think there may have been a door further aft.Pretty comprehensive cockpit with GPS,etc,and looked well maintained .circa 1997.....
edit...beaten by Treadders....slow typing...
