A while ago, I picked up an Aurora button filler on Ebay for a good price (it came from Romania if that's relevant), which was listed as a Selene, though it quickly became clear it wasn't. It is a huge button filler -almost 17cm from top of jewel to tip of nib, very thick, and with a good heft to it, easily the biggest vintage pen I've seen in person. It is entirely without any markings or imprints I can find, apart from the marking for a #5 Platiridio nib. I don't know anything much about Auroras, anybody know much about it? FWIW, the nib is very flexible, the body is celluloid while the blind cap and section seem to be ebonite. Does anyone know the model name, or of any similar pens, as well as a general figure for value? I feel like I may have seen something vaguely similar listed as a "business pen" or something, but can't find anything now. Pictures: https://imgur.com/a/VLo9GLn
