Do you know if they have a maker mark or stamp? As well, did you acquire them as used or vintage in the 1960's?
Thank you for confirming the date and checking for a maker name. May I ask what you are asking for them on Craigslist and did you mention Artolier in your ad?
I think the interest in them may have been that they look like older transportation lanterns. Artolier light fixtures tend to sell at auction for an average of $50 per light on today's market.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
