Good evening.
A Google search led me to this thread:
https://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/15187324/1I bumped it from the archives with some information and questions.
It seems that the Mauser forum would be a possible source of information.
Instead of running essentially identical threads, if you are interested, could you kindly click the link above?
Thank you in advance!
