----- Original Message ----- Since we're 'comrades-in-arms' I was especially hoping to be able to help you out, but alas, although I have some NOS .55" 5-series displays the only .33" 3-series I have are the two-digit SP332s that you already have; I assume you don't need any more? Why not check out the various places that advertise having SP-333s; can't hurt to ask for a quote... I believe Heathkit also used these, although I don't remember which size/type; might be worth inquiring on one of those lists. mike
