I regret to report that my "secret" source for parts did not have a flat mainspring in stock, and did not have a blueprint or specifications for their manufacture... if anyone does have the information, in ANY language, please let me know.

I have a personal friend who is a blacksmith, who might take on the challenge of producing these springs...

I have also contacted Paul Regnier in Switzerland, a recent addition to the Lugerforum membership, about whether or not he might have one of these springs available for purchase, AND if he has possession of the Swiss historical documents related to Luger manufactuer and service... Hopefully one of these attempts will produce the necessary information.

Contact me via PM or, in this thread if you can help this effort.
