Registration marks on metal drawer pull

[8356karen]

I have an old drawer pull that I just noticed after cleaning that it had some registration marks.  Does anyone have any info about them?   I think it may be copper or brass. The  letters in the circle are JUSL   Numbers are 4038M   Thanks

Maybe showing the front side would help.
