Haha that's hilarious, I got exactly the same extras from him when I ordered my 1T308Vs. The black diode is a Soviet
D18 germanium, and the glass diodes are
SFD106 germaniums. The symbol on the D18 is just the Cyrillic letter De, which translates to English as "D".
Those transistors would be good for a variety of drives and fuzzes. If you see a layout on this site that calls for an NPN germ, give them a try. The 2222 is one of the most ubiquitous NPN BJTs in the industry, anywhere you see a 2N5088 or 2N3904 or any other general purpose transistor called for you can pop in one of the 2222s and see if you like it.
Through all the worry and pain we move on
