I used to build quite a few models back in the day. Not a ton, I certainly knew kids who did more and better than I, but it was something I enjoyed. Here’s a couple of certificates from the Revell Modelers Club. Don’t know exactly what years they are, but I would guess late 1970s. Possibly early 1980s, but more likely ’70s. I wish I still had some of those catalogs. I built mainly cars, but also WWII planes and a couple of ships.
