Inside an old pocket transistor radio

[bwanasonic]

Looking inside an old Zenith Royal 13 pocket radio. There a 3 *Aluminum Can* transistors.

2  marked:

H421-13 6980 JAPAN,

and 1 marked 421-12.

There are also 5 of these little 3-legged stool blue glass button looking thingies marked 12112-F.

These parts sound familiar? Anything useful to a DIY stompboxer?
