I have only had a couple of Flues over the years & both had the auto only safeties. Both were from around the 1924 period, one a 20ga the other a 12ga. Both were field grades with steel bbls. I hunted the 20 quite a bit back in the 1960s. At the time I was not aware of their notoriety of frame cracking & it was smokeless powder proofed so fed it a regular diet of the 2˝DE-1Oz load almost exclusively, both factory & reloads. I never fed it any of the 2 3/4DE-1Oz "Express" loads though, probably fortunate.
