The US Navy was paying much more for its submarines.
Here is somebody’s photo of one constructed from that kit,

All it needs is a carbon fiber shell and it’s ready to visit the Titanic.
Too soon?
Nope.
Only a couple of times though…
When I was a kid I wanted one of these so badly. We had a pond down behind the house and I thought this would be perfect to check out what was at the bottom.
My Dad explained how something made out of fiberboard would not hold up in water.
The actual kit actually looks good, though i have no idea if it was worth 7 USD back then. According to online inflation calculators, that’d be 70 dollars today
Yeah, hard to tell. It did promise a little glitz such as a periscope (just 2 mirrors and some cardboard, probably a few $?), a lit instrument panel (implies batteries and a bulb or three), and whatever “rockets that fire” meant. In the real photo there are two red rockets behind the crew compartment. Maybe those were spring loaded and could be released from inside?
I could see an imagination-driven kid having a certain amount of fun with this thing. Although I bet the novelty wore off fairly soon.
you know I feel inflation numbers have been increasingly more bunk but I can’t really point specifically to something but you got your math right feels like this would cost 700 today.
Pretty sure its cardboard
maybe but like paperboard and spunglass furnace filters are like 5 bucks now. Like this is almost 50 euros for a tabletop thing. https://www.schreiber-bogen.com/ships/ships020/71008.php
That has almost as much detail as the submarine in its entirety though.
yeah althouh still technology should allow it to be much cheaper and honestly if inflation makes any gains from technology irrelevant to the average joe what is the point? Its actually something I have been thinking about with a lot of modern technology.
