Hello again. I have this beautiful Sphinx, with a nice flexible Linz nib, from goodness knows when (I'm thinking 50s, just on a hunch). It's lovely to write with, but so far I've just been using it as a dip nib, as I have no idea how to get the filler mechanism working. I've fixed a few lever fillers, but I admit, I've always shied away from other systems.
And to be honest, I don't even know what this is! Is it a button filler with a normal pressure bar, or is it a piston filler? I've worked at the section with dry heat for six months now, and most of my other similarly stubborn ones have yielded, but no sign of this one moving. The button turns very slightly but I don't want to jam it of course. I don't know, if it's a piston, if I should just bite the bullet and see if I can unscrew it, but obviously I'm inclined not to try, as I don't want to break it. There's a dry rattle inside, but I can't tell if it's an old sac or a pressure bar or what. Can anyone point me in the right direction?
By the way, not related to the repair job and filling system, but I'd never seen a feed like this before. It's slit laterally down the middle, and although this picture shows a bit of roughness I think that's just dried ink, and I'm fairly sure it's a factory job.
