The SCA 300 is an open system

The SCA system was developped by a number of companies (all German ?) to be an open system. In theory you can (for instance) use an adapter made in 1997 by Metz to connect to a flash made years ago by Braun.

The following mail is from someone who tried such a thing and verified that it really works.

Subject: interchangeability of SCA 300 adapters
Status: OR

Since you were kind enough to respond when I sent you mail a couple of
weeks ago asking whether a Metz SCA 351 adapter could be used on a
Braun SCA 300 flash, I wanted to tell you the results of my attempting
this.

I took my Braun Ultrablitz 34m down to a shop where they had SCA 351
adapters, attached one, tried it out on my R6, and all the displays
appear to function as they should for TTL OTF metering.  I bought the
adapter, but that was only this afternoon so I haven't seen results on
film yet.

So, here's another datapoint that says you can interchange these
adapters among flashes made by different manufacturers.

The SCA 3000 is, to the best of my knowledge, only used by Metz.
