hello there welcome to my channel my name is Doug and I'm back with another shorty video
now then I'd like to put a quick video together because I get an idea and I want to get it down
quickly just a couple of weeks ago I did a review of the new asvine P20 piston filler and I bought
this pen thinking that it was a look-alike for a momento Zero from Leonardo mostly because of
the similar kind of clip and the similar kind of milk bottle shaped sections but when I did
my review I discovered it is more similar to the Narwhal School kill fountain pen than it is to the
momento zero and as I examined the Pistons and everything they look very similar so I thought
to myself inquiry minds want to know are these the same pen will the parts interchange and so forth
so I've cleaned out both pens and I'm going to use my wing sung 699 fountain pen wrench because
it fits both these pistons and we're going to take the Pistons out and we're going to see if they'll
swap between the Narwhal and the asvine so first of all let's take the Piston out of the Narwhal
and we put the wrench on tighten it both of these are reverse threads so righty Loosey Lefty tidy
so I'm going clockwise to loosen it and we can pull that out and there is the Narwhal piston
and we'll open up the asvine Piston as well again it's the same wrench the same size
the same left-handed thread we're going clockwise to loosen and we're going to pull that out
and let's take the Caps off
so there is the Narwhal on top and the asvine on the bottom so
I'm going to take the Narwhal body and put the asvine Piston into it
and we're going to go counterclockwise to tighten it same thing with the Narwhal piston in the ass
beam I'm going to put the Narwhal in the ass bean and that's what she said that's
what she said there we go and we're going to go counterclockwise and hand tighten it and close
the Piston down and there we go they are complete match for each other threads and everything so
the back end of these pins is identical you can see that the sections are different the threads
are in a different place so the Caps do not swap but what about the nibs let's take the nibs out
there's the asvine nib
and here's the narwhal nib so let's put the Narwhal in the ass beam
and put the s bean in the Narwhal
there we go so here you have the asvine on the top with the Narwhal piston and the Narwhal
on the bottom with the asvine piston and they have each other's nibs now in them completely
interchangeable so my guess is that both of these pens are made in China narwhal is a Taiwanese
company and my guess is that they get an oem Chinese manufacturer to make their pens for them
and they assemble them in Taiwan that's the only way that I can describe how identical
these Pistons are so the Pistons are identical parts and you can't get more identical than that
unless they're made in the same place so all the kaveching that twisby did a while back about uh
the Narwhal piston being a copy of theirs well I think twizby has theirs made in China as well
and just in case you don't believe me here is my asvine P20 with the twisby echo piston
and my twisby echo with the asvine Piston installed Perfect Fit that's my two cents
on it anyway and there you have it thanks for watching don't forget to subscribe I made this
