But in some instances, I am not sure it would be possible. Today you would have a helluva time trying to build a 1940s radar set, or even one built in 1970. Technology has moved on, the machinery to make such things doesn't exist, the know-how is pretty much gone too. And, of course, why in the world would you build something like that since it is far inferior, and should cost more?
Star Trek (Original): Episode-"Botany Bay"
Scene: Our intrepid heros of Kirk, McCoy, Scotty (and maybe some others)
Kirk-"Mr. Scott, do you think you can get things working again?"
Scotty-"Eye Captan, These are tran-SIS-tor circuits, solid state not our modern tech. I can't wait to tear into this and study up on this old technology"
DISCLAIMER: Not exact quotes, but the important parts are there. The Original Series was in the 23rd century (2200's), Next Gen a mere 76 years after that (24th Century, 2300's). So lets say 250 years from when the Botany Bay was built is when this happens in that storyline.. 250 years and what, 2 tech levels for "1990's" tech to be so out of date it's only been heard of but never study it?
The original series had AM/FM transceivers, video screens, etc. All done with 23rd century tech, but still a viewscreen could only be made so small before you couldn't read it, communicators so small you can't effectively utilize them, and phasers (energy weapons) so small before you couldn't effectively hold them in your hand.
And the process of making the plastic bodies, the knobs, the housings, etc probably still cost the same they did 100 years ago (unless inflation set in again).
