Picked this up today. A small grail item in my eyes, but only 2/3 of it, unfortunately... As you can see, no cap. Did the french use a different threading for their de because the old type caps I have (which this pretty much had when it was new as far as I can see in photos) didn't jive with the handle. I did get an old german 3 piece travel and travel handle/old type cap it used to mate with the baseplate just fine and it pretty much looked as these all do when intact. And it is as aggressive as all hell. The french handle is just not wanting to work with caps foreign to it. I had a german three piece that was this way as far as the handle only wanting to work with its own head. Anyway, pics below. I will ul better pics later if anyone cares. Can someone on here who has one post a pic of the underside of the cap?
