Hey Gang,
I've had this #120 plate variety in my collection for a while, but I have never really narrowed down exactly what it is. The most obvious feature is a thickening of the side of the frame, through the centre area. I'm using George C. Marler's
The Admiral Issue of Caanada as a reference, but the stamp doesn't appear to match any of his descriptions 100%. Here's the closest bet, I think;
Quote:
1. Thickening of the right side of the frame from opposite GE to opposite leaves 2 and 3, with a mark above the first A of CANADA and a short extra line below the E of POSTAGE - there is in the right margin a mark opposite the top of leaf 4. 2L2 (Marler, 410)
My stamp shows the thickening of the frame and a small trace of a line under the E, and a trace of a mark above the A. However, there is not a mark in the margin near leaf 4. There are three other re-entries/retouches described with similar thickening of the frame, but I think I have ruled out them all.
So let me know what you think. Re-entry or just retouched? Anyone else have access to Marler's book, or any other resource, and want to offer up an opinion?

Showing the thickened frame and the small line under the E.
