Follow-up: I did rummage around and found a couple of the extracting inserts D as well as the lever C. Have not found an adaptation insert E yet. I also confirmed that both tool pin ends will grip a 14t cog and probably a 13t cog. The photo shows lever C holding a Suntour 14t. The lever F at the bottom is as found - grim rust on almost everything. Some salvageable, some not.

As a bonus bauble, notice the nice VAR chain break tool. They don't make em like that any more.
