GE Educational Projects

I saw this box (actually 1/2 of a box) on Ebay but was intrigued:

I had no idea that GE had a series of educational projects for kids like this - That led me to a search which found this manual on an interesting site in Spanish:

The GE analog computer project in turn reminded me of this:

The American Basic Science Club Analog Computer - I got one as a kid - not sure what happened to it.  I *think* I still have the ear phone but not the cardboard box.  I recall seeing it in Boys' Life or one of the other magazines in an ad like this:

 

I must have seen this ad (in a Sears catalog ?):

because I was expecting a meter but I got the one shown in the Boys' Life ad with the ear phone :(  Here is the inflated price:

Here is a site by the son of the man behind the American Basic Science Club:

Lots of docs up there for the various kits.  Later on I got a Pickett aluminum slide rule as a present which didn't require any batteries :)

I was hoping to get into this area of educational kits but it's really a tough market - if things are done cheaply you end up with American Basic Science Club cardboard but if they're done nicely (like the Raytheon Lectron:

the cost grows exponentially.  Educational stuff is a very price sensitive area that gets slaughtered by the whims of the tariff-taxers.
