I can remember my first exposure to scale modelling was a friend in elementary school bringing in a Saturn V /Apollo spacecraft. (This was about the time of the first Lunar landings.) It was so cool, as you could separate all the various stages and even open it up and extract a tiny Lunar Module. I asked my parents for one and I think for Christmas or a Birthday I got a kit. Unfortunately what I got was not the same thing. What they found instead was the Apollo craft only, which consisted of the Command Module, Service Module, Lunar Module, and the adapter section that housed the LM. Also included were 2 square bases, one of which held the Adapter and had a few clouds molded on it, and a Lunar section pitted with small craters and imprints of the landing pads for the LM to sit on. Also included was the escape tower. The LM could be separated into it's two parts and the CM separated from the SM. The service mod had a door that opened to show the fuel cells, tanks, batteries and other details inside.
Though not what I wanted, it was pretty cool as well. I put all together pretty quickly with minimal painting and didn't even bother with any decals. As far as a work area? Well the kitchen table was off limits to kids activities, as was much of the rest of the house. My work station was sitting on the edge of my bed using an old beat up folding TV tray.
Later kits and paints were purchased with allowance money or were gifted. It's a good thing kits were cheap then as Dad didn't make a lot of money.
Early kits I remember were: P-51, P-47, a Kingfisher, a Stuka "Tank Buster", British Phantom, the USS Missouri battle ship, an aircraft carrier (WWII era), some cars and trucks and even a few commercial airliners. I also remember a AC-47 gunship with 3 Gattling Guns pointed out the left side of the aircraft. It was molded in a camo pattern (not sure how they did that-maybe it was prepainted, I don't know.)
All these kits were tossed out as I "grew up" as most had broken or fallen apart. (Tube glue was not always permanent)
Now years later, it's an adult hobby, with high-tech kits, detail parts and the the investment of probably thousands of dollars in kits, tools, paints, books and magazines, and even the area to work and display projects.
