hi, i have a lead in the UK to buy tritium discs size 10mm,15,20,30, by 3mm thick painted with phosphrous one side these are not perfectly round they have a small glass fill nipple 3mm high on the the 3 mm side, not so sure about the price but will be cheaper than a sphere, as it's due to numbers just shout here for any interest :thumbsup: cheers DocD
