I'm looking for iron gall inks in addition to my current ones.

I have five of the KWZ brand, the R&K Salix and Scabiosa, and ESSRI. All have performed wonderfully, most have very nice shading and sheen on Tomoe paper, and I've experienced no problems in my pens, whether eyedropper, converter, or piston-fill.

Other than the Diamine Registrar's Ink, are there other brands?

These will not be used in vintage pens with sacs or older piston-fill pens that aren't easily cleaned.

Thanks for any suggestions.

Cheers,
Sg
