To attempt a reply to at least a tiny part of your questionsRed scarf with no period after the F.
1. Period in signature or not - yes, there are micro differences between exemplars of the same design, that does not mean one is a fake, this is particularly true of the older designs. Ex - see bottom right of galloon - over the Rs in the blue scarf for ex, the galloon has a bit of blue in it but I dont see that in the wine color
2. Can anyone resolve the authenticity issue for you ? Try a paid authentication service ... There is no published list of the micro differences and what they mean. And yes, different paid experts may have different opinions - see Orange Turandot thread - customer paid for 2 authentications - one said fake , the other real. Lots of good photos in that thread, better than I can repeat here.
3. Which cws in original issue? No definitive list exists and most sites only give the issue date and no conclusive opinion about which cw in which year. Ask at HSCI, but I don t think there is any attempt there to state that the blue cw is from 1963, only that the design was first done in 1963.
4. Experts can have different opinions on dates - note that lists at various sites have conflicting dates - you could email each site to find out their source.
5. You can ask Hermes via the Contact Us form on the web site. But, you will have to get in line behind me, they still have not answered my query from 3 weeks ago ...
6. Should you worry about a period ? My opinion - Hermes scarves should give you joy (where did I get that from ? lol) if you are worried about one of yours, then maybe it is not giving you joy ...
7. And best of all, lol. My 2006 post on my Ludovicus - too funny. I did not know how to take photos then and cropped off the signature - ergo, my comment that mine is unsigned. And I did not know how to find the copyright in those days. So, mine has signature & copyright. You cannot believe every thing on the web lol esp. old stuff
