Doesn't need to a perfect match, but something close enough in style of the letters. It seems really familiar but I can't figure out where else I've seen it but on a project I'm working on.

Trajanus  Suggested by APlaPi 

Very nice looking 'S', but I couldn't find any similar..
Something close could be Trajanus

NOT THE FONT

Thank you! Close, indeed, but lacks the rounded corners and edges. That's been a major stumping point. If I can't find a match, Trajanus will certainly suffice, but I'd love to find a font even closer. Could be a variant on that font too.
