I had the same decision problem with my Bf109F. I'll probably end-up using the engine in a diorama with another '109, with the engine either on a work stand, or on a hoist, alongside an aircraft that still has it's engine in place. The idea will be to show either one engine removed and not yet taken away, or one waiting to be changed.
I should have some pics of engines in various states - as a complete pod, and on delivery cradles etc, for '109s, and the '110 would be very similar. Give me a shout if you need them.
