They would sell at my house, I love those sets!
TJ...
Show 'em the lift bridge on your layout built from Erector pieces!...

For a while our LHS sold the new generation of Erector sets. They were hard to get through traditional distributors, as I recall. I don't recall any large make-a-bunch type kits as the big red metal boxed Erector sets of yore. They were mostly small, single project items...that grandparents bought for the kids' kids about this time of year. Our LHS hasn't had them available for several years now.
My guess is that a 3D printer and hours of putting together a project program on the computer to run the parts thereof would be today's analogous 'Ooh-Ahh' on Christmas morning. Round headed machine screws, square-sided nuts, sheet metal plated/painted parts?....not 'cool' anymore.
Re plastic blocks of yore?... It's Lego this, Lego that nowadays. To that company's credit they've nursed their brand through a variety of challenges, special mega-displays, current events, etc., etc., blah, blah, to have become pretty much a world-wide institution. Doubtful they'll run out of 'gas', dry up, and go away for several more generations....if ever.
Ah, yes... One of my most memorable events with American Plastic Bricks was stepping on one while barefoot! Not fun.
Tinkertoys, Lincoln Logs, wood blocks, Erector sets....blessed to have had them all as a kid. Much better than staring at the Boob-Toob...or similar...nowadays. Building model railroad items from kits...or scratchbuilding from this and that...was the logical FUN progression back then. Now the 'fun' is being able to afford things ready-to-run....I guess.
Yesterday wife and I were at our LHS picking up some items. Walking through the R/C airplane department the shelves were well stocked with the ARF's...Almost Ready to Fly...which fundamentally require one skill: attaching wings to a fuselage. (I asked the manager if he had any WOOF's to go with the ARF's? He said, 'What's a WOOF?' I said, 'Worth Only One Flight, of course!'...as is often the learning-curve nature of that hobby! TEHO.
