well, keith, that clarifies and condenses things for me, thank you...
which brings us back to an old topic..re heat treating of shotgun frame parts, in a vain effort to duplicate long faded factory case colors...
considering that frame metal alloys varied through time and manufacturer, plus original heat treating specs for most gun makers have been lost, one must conclude that those engaging in the black art of shotgun frame parts re heat treating are only guessing as to their practices, based on their experiences, based on trial an error...
least, that is what old ed taught me...
