Gents, For what it's worth, I've started a Bessa repair Wiki with the intent of offering a place where Bessa knowledge can be consolidated:
http://bessar.wetpaint.com/

Feel free to use it or ignore it as pleases you. It has pointers to the articles you've mentioned above.

I've posted information about this wiki several times on Rangefinderforum.com and the information has never been deleted.
