Sorry can't help with the model - someone more knowledgeable may come along. As I'm sure you will have seen, there are quite a few Fler and Fler type chairs for sale on eBay - the ones that seem to sell best are the ones with the lovely teak frames - it is a bit hard to tell from your photo but I presume the brown stuff is leather / leatherette / vinyl? A lot have very high expectations and fail to sell; I would only be guessing at $150 maybe $200 the pair? I assume they would be Pick Up Only, which depending on your location, may limit your market. If you cannot identify the particular model I don't think it would really matter - it is the LOOK people are after, unless it is one of the really iconic Fler designs like the SC55. Google Fler chair designs - images for lots of examples. Good luck if you decide to sell.
