Great post.
And it Highlights just how few of these are still out there.
This is why it's such a shame, from a firearms collector standpoint, when people go and deactivate them, more or less destroying 100 yrs of history; all for the sake of having what is essentially a toy. If you HAVE to deactivate one due to your country's laws (and not just because you don't want to go through the trouble of getting the proper permits), than you should hold out for one of the chrome FBI models as the historic value has already been more or less destroyed.
Sorry if that sounds a little harsh, but it feels like a kick in the gut every time I see one of these WWI relics destroyed all for the sake of a prop...
BTW Andy, are those lovely pieces yours? Both look fantastic. What year is she? I got a 1917 myself. Your No1 looks like it must have taken a hell of a drop somewhere in it's life, as the trigger guard looks just slightly flattened. Not easy to bend that old steel.
