I use this site for datasheets, it's pretty good.http://datasheetcatalog.com/
Transistor Replacement Guide - 1973 GE on bunkerfodoom.com . It is 250MB pdf, unfortunately not individual JPG pages which can be conveniently looked through. Someone with a newer version of adobe could possibly d/l it and reduce the size greatly. Inside is a cross reference to GE universal types with their specs. Not sure if it is useful, maybe as much as an NTE catalog.
C2086 (nor 2SC2086) is not inside.
2N2222 is inside. That's one of the most popular types ever and is still made, and itself should be directly on the internet. It has its own wikipedia page.
Check the brand carefully, because it has become so generic-ized that it could be rated 30V to 40V, 0.8A and be in several packages, depending when and by whom it was made. The -A is usually 40V, the plain one is 30V. Generally it is a 30V, 0.8A, 0.5W NPN transistor with an hfe of about 250-300.
It's best to find several transistor books covering the time span, just like having several editions of each tube maker's books. I remember dialup, used to wait for bedtime to start large downloads.
