I have been asked to get a digital transfer from what I believe to be a "Flexi disc" (thin green plastic /vinyl disc with a square hole). The only complication is that, as far as I can tell, these were LPs and, therefore, no earlier than 1948. The date on the disc, however, is '43. We have an osmium stylus (which we use for 78s) and a diamond stylus (which we use for LPs). What stylus should I use for playback? (And if you have recommendations for adding to my stylus supply, I would welcome that as well, though I may not be able to do anything about it just yet.) Barbara Barbara Need Manager
