Way back in the 60's, when I was a little boy, I was (of course) enamored with Star Trek and other shows like that (The Outer Limits, for example). Towards the end of the 60's you could get decent sized models of the ships from Star Trek. I had both the Enterprise and the D7 Klingon Battlecruiser.
I also had large models of the battlecruiser Hood and the German battleship Bismark. I've always been fascinated with the German navy in WW2 and I had various models of the ships in their fleet, including the aforementioned battleship Bismarck as well as the battlecruiser Scharnhorst, the pocket battleship Graf Spee, and the heavy cruiser Prinz Eugen.
When I say decent sized, I mean they were like 1/350th scale, upwards of 2 feet long. Not like so many of the models these days that are incredibly down-sized. I'm also taking about models that you would put together yourself, with Testers Glue and then paint them. Sometimes they were a little difficult for a nerdy 7/8 year old dork, but I got by. Good times. :)
Fast forward to 2022. I was looking around the usual places like Amazon and Ebay. I was pleasantly surprised to learn how many models are out there now and unpleasantly surprised by how small (many are 1/1000th scale). Then there's the prices. It looks like models of the size I remember from "back in the day" are now $200-300.00. Ouch.
Anyway, I did find a 1/1000th scale model of the original D7 Klingon Battlecruiser from TOS for a good price on Amazon. It's snap-together and pre-painted, so nothing like I remember but it makes me very happy to see it in my man-cave. :)
