S-90 q?

[ayebaal]

I've had my domestic German (not ROW) S-90 for 35 years. Swaped the 022 for an 050, worked pretty good. Now I'm thinking about going back to the 022. My question to the group is: How do I know what I removed 35 years ago is the real 022?
There is no number on it that I can find. It's cast iron, has the 2 piece points, and the little paper insulating strip between the point spring and the wall of the distributer body, is mechanical advance, but no number. All the other VW, 911, and 930 stuff has a number but not this one.
Can anyone shed some light on this?

Ask the boys over at the 356 registry. Somebody there even rebuilds them.
