Larry, the first Idéals did not have a safety. You close the gun uncocked and cock it
by pulling the lever as you mount to shoot. Forget the safety.
Lapin, the sling disconnect, as you surmised, is steel, and not that mild. I had to go at
one and it was quite hard.
It should be noted that the original patent for Idéals is from 27 October 1887, and it
had a "normal" trigger guard. The "eyeglass" guards appeared in the first guns and
were discontinued in 1909.
Here is mine with "classic" trigger guard.
