Something to note, both two tone and three tone nibs are gold nib with different color plating. If the nib has been refurnished/polished, then there is a chance that those platings were removed in the process and resulted in a single tone nib.
Celluloid Pens were produced back in 1950-60, but please note that due to the nature of celluloid, their exterior and interior diameter may differ, resulting in different fitting of pistons per pen. (cork is still used for vintage pen pistons since there isn't a one size fit all O-ring for these pens)
They were also handmade pens, so the length may also differ greatly.
