There’s an advert at [www.astromart.com] to sell Clyde Tombaugh’s amateur telescopes; I’d love to visit it, but I’d never buy it even if I had the money.

I much prefer the trend for lighterweight, modern mountings (if the Dobsonian can be called modern) – compare:

16″ f/10 circa 1960: [www.astromart.com]
16″ f/3.5 circa 2002 [home.planet.nl]

…the latter is a lot more usable in these days of light pollution and hauling-your-scope.
