I hope you'll get the old stuff!
When I was 7 or 8 I've been able to keep our old 200A fuse panel (with a main breaker). Unfortunately my parents threw it away a few years later...
And if you can get the meter socket, you could go to your local power company's offices and ask if you can get an old meter! With some luck you'll find a 120V meter, but a 240V one will work fine as well.
