Retiree finally getting around to some modeling projects that I collected kits for throughout my busy career.
Last prolific kit modeling period was my teens. My friends and I built WWII 1/72 aircraft for "run around" wargaming.
Got into N scale railroading in my 30's and built several layouts. Switched aircraft interest to 1/144 in my '40's to have an airport train layout, which I completed in my '50's.
My retirement modeling has been focused on subjects where I can display planes and trains together in a model train (layout) diorama. The planes have only been pre-built or pre-painted so far.
