I bought a 1914 Negretti & Zambra Tel. Sig. Mk.III in good condition for a very good price. It’s currently with a specialist repairer for a strip & clean and should be back this week 😊. It came with a high power eyepiece - does anyone have a suitable spare low power eyepiece they would sell? I don’t know whether an eyepiece from a Mk.III by another maker would fit?
