Sewing machine Mundlos in good conidition, work's, has all keys, but i can't find the year

The surround of the cameo is silver and has, what looks like, diamond chips. It has a hinged loop so it can be worn as a pendant as well as a brooch. The pinky orange part is translucent when held up to the light( see photo ).The carving is very fine and detailed

ive taken some pictures of what i think are the older ones but they wont all fit in to 5 pictures

AGAIN WE HAVE A PIECE THAT WE KNOW NOTHING ABOUT. HAVE SEARCHED INTERNET ENDLESSLY TO NO AVAIL. IT IS PEACH IN COLOR AND LIGHTLY FROSTED WITH A FLORAL DESIGN. SMOOTH BASE, NO MARKINGS. ONCE AGAIN THIS COMES FROM SOUTHCENTRAL IOWA, SHE HAD IT FROM AT LEAST 1950 BUT GUESSING LONG BEFORE THAT.

I have a 7 jewel 18s Elgin Pocket Watch that was made in 1897.. The SN# is 7283508. Runqty is 10000. Name is ATL..

i can't make out the mark on this nor have i seen anything even close. i believe it to be an early American piece. i don't know what the circa is because it belonged to my grandmother... could be the 20's up to the 50's.
