Hello,

I just completed the first version of a page about the Holland Pen Company (sorry, the page is in Italian, I'm not good enough to write in english) but I have some doubts.

As always I collected the information from internet, and from a Lambrou book, but I got some conflicting dates, so I'm asking here.

The first question is about the hatchet filler, according to this article it was patented in 1915, but according to this other one first pens using it started to appear around 1908/1909, and it seems strange to me that it was patented after putting it in to the market.

The other discrepancy is about the Holland company end, the first article says 1950, the second one the end of 1970s. Probably the two date are referring to different events, bud I'd like to know if someone has more detailed informations.

Thank you in advance for any help.

Simone
