The modern reproduciton that I have was made by DaMart Company.
I found this web site in Engalnd:

Rocket Radio (Reference #D4025)
It receives radio signals without using batteries! In the late 1950's,
kids learnt that the magic of radio could be achieved without batteries
through an ingenious gizmo known as the Rocket Radio. Now it's back! By
attaching the antenna/ground wire and tuning the nose cone, a handful
of AM stations can be received and heard through a crystal earphone. An
informative booklet will help curious minds understand the science
behind radio transmissions and crystal diodes. For ages 8 and up.

The show a blue one, but mine is red.
My sister tore mine up back in 1960.
She bought me one in 2001 for my 50th birthday.
My orignal was blue but I didn't complain.
It works pretty well, but I found a site that has some improvements,
but I can't find the $#%^ URL right now. I never got around to
making them, after all why complicate something simple that really
works. When I find the URL I will post it here as a new post.
