Sheaffer IV conversion

[Invicta]

Would anyone be able to advise me on conversion of the IV to a piston or aerometric filler. I don't like cartridges.
Any help would be appreciated, thanks

There's always this quick and dirty conversion: http://badgerandblade.com/vb/showthread.php/241399-Squeeze-sac-filler-mod-for-cartridges

If it is the odd sized Lady Sheaffer this may fit: http://www.peytonstreetpens.com/sheaffer-fountain-pen-button-converter-nos.html

I hope this helps.
