Riga 17: Riga 17:  
Although some book reported that the celluloid was introduced on the market by [[Sheaffer]] actually the first American company to have used it extensively in its production was [[LeBoeuf]], who used it for its fountain pen starting from about 1920 thanks to a patent ({{Cite patent|US|1302935}}) for the production of pipes in this material, the [[Conway Stewart]] contends  this leadership, asserting that they were the first manufacturer to have produced (still in those years) the first pen in celluloid.

In realtà esistono riferimenti alla produzione di penne in celluloide fino dal 1905<ref>David Nishimura in [http://www.fountainpennetwork.com/forum/index.php?showtopic=136998&st=0&gopid=1360934&#entry1360934 questa discussione] fa riferimento ad un articolo del 1905 che parla di penne in celluloide (nera).</ref> ma in questo caso si tratta comunque di celluloide nera, e non di quella celluloide realizzata in molteplici colorazioni e motivi che diventerà il materiale più significativo a partire dalla seconda metà degli anni '20.

In fact, there are references to the production of celluloid pens up since 1905<ref>David Nishimura in [http://www.fountainpennetwork.com/forum/index.php?showtopic=136998&st=0&gopid=1360934&#entry1360934 this discussion] refers to a 1905 article that speaks of (black) celluloid pens.</ref> but in this case it is still black celluloid, and not the one made in multiple colors and patterns which will become the most significant material from the second half of the '20s.
