German/Central European SL mark on silver buttons

[cgbeard]

I've got a set of ten clothing buttons bearing the '13' and 'SL' marks. The only reference to an SL I can find comes out of England in the late 1800s, but the 13 is leading me more in the German direction.... Has anyone seen this mark before? Thanks!

HEllo!
So possible, that button made by Libay Sámuel from Besztercebánya (now BAnska Bistrica in Slovakia) He used this marks in buttons and smaller items. Ha was famous about his filigree art. For example made a filigree bust about Napoleon and the hungarian king I. Ferenc.
