Welcome aboard, Phil! A really difficult one...it does look as though there are some interesting features. However, I would say that, what looks like an upper back-curve of a three, is just a little too inconsistent with the shape for a full-shaped 3? Also, the little prominences at the front top-edge, and front-edge, of the 5, look a little damaged/clogged die, cruddy, a little like the edges of the 4? I don't know, would need a little more experience of type, which is not in short supply on here! A die-study would help!
