Hi Julie
I think its 451 If you look at other 5s the top bar slopes down as does our subject. If you look at the 7s the top of the down stroke starts very thin getting thicker as it goes down. It also goes further than the base line. A 1 is the same thickness all the way down. Our one, the slope of the 5 touches it making it look like 7
Just to make things worse, FMP transcibed it as 6/451 ie a Vl, instead of Xl
