I am missing something on this stamp. Here's what I think I have:
- #10 Orange Brown
- Plate 1e (or 1i)
- guide dot in the LR
I looked at all the possibilities and none are even close.
I see additional distinguishing characteristics:
- outer right frame line goes too far
- narrow spacing between the left frame line and the diamond block
- recuts in the LL and UR triangles
- possibly a bend in the top frame line
Perhaps this is an 11 and not a 10?
