Ah, memories, memories!
Like Mr. Grubby I have "put down" some models for my retirement - mainly the Airfix 1/24th scale WW2 models:
Me109, Spitfires 1 & V, FW190, Hurricane, Stuka, Mustangs D & K. I also have enough Airfix motors for them all (good old ebay!).
Now I will have to acquire the Mosquito! I suspect that they will never get built, though.
I built a HUGE quantity of models over about a 10-12 year period (up to university), from warships to space models. One of my favourites was the Airfix B29. I loved that aeroplane.
My final interest was in the arms and armour of the Wehrmacht, and I had a huge collection of vehicles and weapons - some scratchbuilt or heavily modified - ranging from motorcycles to King Tigers, and nebelwerfers to railway mortars! All in 1/72 or 1/76 of course.
The best thing I ever discovered was liquid polystyrene cement! Bloody good for making models with, too
