Pilot 743 nib compatible ebonite feeder has been developed.
this feed is only compatible with specially designed grip section.
after completing the 742 feeder, i went on to continue working for the 743 feeder.
when developing the 742 feeder, I studied the intricate form of the pilot nib root form.
so working on 743 was much easier, thanks to the experience.
surprisingly, 742 and 743's nib root form is exactly identical.
so i can actually install 743 onto 742 ebonite feeder.
however, due to difference of the nib length, actual use is impossible.
so, using 742 feeder as base, i changed important parameters so it will fit 743 perfectly.
consequently, development was facilitated.
completion of this research means i mastered developing ebonite feeder for pilot nibs.
next i will work on ebonite feeder for Aurora.
thank you.
