    I would say you would have a better luck asking in the Darkroom B&W forum than here.

    The Sandy King's fixer formula resembles TF-2 in terms of the simplicity of ingredients.
    It is scaled down in terms of thiosulfate concentration and sulfite accordingly and adjusted with a bit more carbonate to give slightly higher if not similar ph.
    I would say the stock should keep for few months, TF-2 stays well for six months.

    IMO, I wouldn't risk it for more than 10 8x10 prints, since kallitype contains iron and silver it can exhaust fixer quickly.
