Rob:
I really didn't glean any info on the Funk safety, but I did learn how to remove and insert the removable trigger plate on a Neptune as during the 1st GGCA show & tell in the a.m. Saturday a fella watched Steven Meyer remove one with some assistance. The the fella was showing his brother-inlaw at Mid-South Guns table and without permission removed the trigger plate which is held in position on the triggerbow guard end by a rotating pistolgrip end cap. After retrieving it from a British cap, I was blessed and it fell right in.
The following 1960s-1970s vintage pic is of Alfred Schlegelmich, performing a re-barrel of a Meffert drilling owned by Mike Ford, who sourced Helumt Kerner for the tubes which all but had to have been forged at Heym. Helmut Kerner was the grandson of Emil Kerner(Aechte Suhler Jagdwaffen -1904 advert -
http://books.google.com/books?id=JeMqAAA...uhl&f=false ) and Helmut Kerner was also the grandson of Immanuel Meffert on his mother's side(this may not be exactly correct but is close and I'll work on the links). Alfred Schlegelmilch wasn't a master by worked at Heym during the week and at Walter Grass's shop on Saturday. Heym sourced Grass for installing scope mounts and the like.


Kind Regards,
