Hi Scott,
Firstly, my gut reaction is that this is likely to be a John Luxton design, largely because of the style of design of the cutting combined with the techniques used.
However, the answer is possibly in the backstamp, since "Stuart England" had a number of versions - so which is yours??
If you are not able to photograph it (since it can be very difficult) perhaps you could describe it. Is the type face plain, or with serifs; is it on one or two lines; are there any curls, or extras to the letters, etc., etc.?
