Probably not much help, however, interestingly, just came across the below example on the following auction listing/website, please see (Lot number 455)
http://www.ukauctioneers.com/auction_houses/369/sales/5209?page=19Unlike many of the other examples I have seen, there is another mark on the base of this one, if you look at the second photo for lot 455. There is a logo and wording, which whilst I'm not 100% sure I think it reads 'Antichi Arte'. I believe this translates to something like 'Ancient Art', so would lead me to infer probably a more modern piece, taking inspiration from an older style. Regarding the logo, on reflection, I think this is probably, just 2 capital letter A's for Ancient Art. Hope this a little.
