The TPF1 seaplanes are already sitting on my hard disk in a converted, expanded and strongly revised set. But there are no proper docks yet fitting their timeframe, making a release kind of pointless. At some time, I might get to reworking the TPF1 ones for 2, but if and when this project will be started, I do not know yet.
