FORGET ME NOT ENAMEL Antique Solid Silver Nouveau Victorian Love Token Pendant

Description

I am selling a collection of antique chatelaine and jewelry items as seen in the last photo so please see my other offerings and check back!
ABOUT:
Old and beautiful round charm with enameled forget me not flowers in blue with yellow center and green leaves.  Lovely antique engravings on the front but I don't know what it represents - it looks like "M. & Eichen", perhaps a name?
Antique piece that I acquired in Austria.  I purchased a small lot of these so please see my other offerings along with some antique silver charm bracelets these would work well with!  Smooth undecorated back which could be further engraved.
Chain in photos not included.
MARKS:
Hallmarked on the loop but I could not decipher it.  Tested and guaranteed solid silver.
MEASUREMENTS:
The pendant measures about 18mm wide.
CONDITION:
All my pieces are pre-owned and in estate condition.  A few areas of wear to the enamel and the text is small but still legible.  Some nicks, surface wear and scratches especially to the smooth back.  2 spots of discoloration from age at about 5 o'clock and 11 o'clock more visible under magnification.  Some spots and scratches to the back as well.
Due to age, please note this is not a mint condition item.
Still many years left in this old beauty from an interesting period in history.
I dearly love, collect, use and sell antiques so please check out my other listings and follow me - thanks so much for stopping by!
