I am still learning but have inherited this silver shoe. I have been trying to find out what it was used for and about when it was made. Thank you for any help you can provide. I can provide more or larger photos if needed.here is a link to a top view
Hello, looks like a pin cushion without the filling. The 800 stands for the fineness, the other three marks look like pseudo-marks. Probably a maker from the German Hanau region. Best wishes, Bahner
