This pen was found during the demolition of an old author's home. I have only been able to find one remotely like it, and zero information on it. I say remotely because my piece has not only the gold accent "grips", but gold ends as well. Also, mine has the classic "head" stamps on the metals vs. the more current numerical values as far as purity and kt's. It is made if France, and just below the writing there is a very, and I mean VERY tiny hand engraving that says LZ 11. I've had a few people look at it, and it has us all baffled due to it's ambiguity. If anyone can shed a little light on this mysterious pen, we'd all love to hear about it.
