Hi Rugser!

I can read SMK Gamma too! Bust is B4, laureate, draped and cuirassed. But I think I can see clearly an C (O?) behind the head. And this position is too high for the legend CONSTANTINVS! In that case the C (O?) is awaited much lower, I think. So I vote for FL IVL CONSTANTINVS NOB C or FL IVL CONSTANS NOB C.
