Today I was given a 1935 Mabie Todd Jackdaw fountain pen. It has a 14ct gold nib and is in quite nice condition overall, but the ink sac is perished.
Would anyone happen to know the sac size for my pen? I've had a look around but can't seem to find anywhere that has the correct sac size... by looking at it, maybe a 15 or 16?
Also, if anyone might have any more information on the pen and would be willing to share I'd be most grateful; so far, I have found that it was mostly used as a school pen.
Thanks very much
