Here is a typical known Maltese mark to compare to your mark. It is taken from an earlier thread here (
http://www.925-1000.com/forum/viewtopic ... ese#p60982):
If we assume that the Maltese mark shown is typical for the 18th century (which may not be accurate), then I would argue based on the previous discussion:
Your mark is not Maltese:
. Your Maltese cross mark does not match proper Maltese cross mark (too fat in the center).
. Your mark does not include a purity (e.g. 917)
. Letter A is not one of F, R or M (the Maltese marks described by Denaro)
. BUT: this is based on incomplete web search - maybe your marks actually do make sense for Malta - you need to get the book by Denaro "The Goldsmiths of Malta and Their Marks" by Victor Denaro, 1972 (it is available at Amazon but expensive; maybe try to get at your library?).
From the pictures you provided (not necessarily reliable, I know), your piece does not really look 18th century to me:
. Bead pattern around rim of base appears very regular - too perfect both in size of beads and spacing between them.
. Base and candle cup appear to be perfect circles and no signs of being hand-made - too perfect for 18th century.
. Candle cup does not look 18th century to me - size, flare, shape and bead around edge of candle cup all look later.
Why Hanau:
. Your mark combination doesn't make sense for known countries (unless Denaro proves this wrong)
. All the marks used on your piece (fat Maltese cross, fleur-de-lis, letter A, and letter combinations) were used by known Hanau silversmiths.
. Tremolierstich is typically (exclusively?) German.
. Some Hanau silver is very well made (based on samples I've seen online and in person - I don't agree that it is always crude).
. If not 18th century but 19th century (as argued above), then your piece would almost certainly be Hanau.
Of course this is all based on my complete lack of knowledge of Maltese siilver, and from pictures which can be very unreliable. But if it was my piece, I would start from the assumption that it is Hanau, and try to prove otherwise. I suspect you'll need to get the Denaro book to try to do that.
