GAB Unmarked - Opinions and Possible Maker

[5ribbonbar]

Looking for some input as to whether this GAB is original or not. Someone told me it looked like an OSANG piece but I am not even sure they are a maker of the GAB...these badges are not my specialty so I am reaching out for any opinions. Thank you in advance.

I always confuse the two, but I'm pretty sure it's either an Assmann or an S&L. I'll check when I get back

Should have just gone with my gut that it was an S&L
