I learned a few things:
- A CZ Duo striker spring with a few coils cut off makes a handy substitute Dreyse striker spring.
- The striker was not, in fact, broken. The cocking indicator was a separate piece, which had gone missing some time in the near-century since the gun was built.
- Shannon is a nice guy who is quite capable of turning a piece of steel into a new cocking indicator.

Machinists are awesome; I am in awe of them. My talents (such as they are!) run towards language. People who can visualize materials in three dimensions and then make them real, that blows my mind.
Shannon as in the nice guy who can give me the rail thickness on your reciever?
Very cool!
Question: how did he know how to make a new one if the old one was missing?
Dimension drawings.
(It's a well-equipped shop. Too bad there aren't any Frommer Stop extractor drawings...)
Measure the hole it is supposed to go into. The make the extractor slightly oversized, and start filing until it fits ... which is exactly how it used to be done.
Have him make three or four, so you screw one or two up in the process.
Maybe someone like Merv Broten would have a drawing of the extractor you need?

I meant an actual technical drawing not an exploded view that just teases you.
Pick, pick, pick... ;-)
Found a Gun Broker auction of Frommer Stop parts from April but the bolt was missing the extractor. :-(
Maybe some kind soul who owns a complete FS will lend it to a machinist for fabrication of a few spare bits...? (There are a few CAD/CAM operators in the Washington Hometown Forum of AR15.com.)
