Transportation Coil #2136 Bread Wagon Two Block Tag Sizes

I didn't find any posts on the two different block tag sizes for #2136 Bread Wagon coil. So I thought collectors of this popular series would be interested in this.



On the left stamp the block size is approx. 19.5 x 23.25mm and on the right it is 19 x 21.5mm. Based on ink color and gum type, the left stamp was printed on the C/D press and the right on the B. On the left stamp ink appears more yellow than right stamp and gum has horiz. striations. Right stamp has gum with diagonal striations.

The OP is correct. Five plates were used to print these coils. Plates 1 and 5 were B-Press products, plates 2, 3 & 4 were printed on the C and/or D presses. Also, three different papers were used in printing these stamps

Just adding some info...
From my examples of these PNC singles:

Stamps from plate #1 have the smaller size block tag.
Stamps from plate #s 2, 3, and 4 have the larger size block tag.
I do not have a copy of a plate # 5 stamp so do not know, but if plate # 1 and 5 were from the B-Press, then I would guess that plate # 5 would have the smaller block tagging like plate # 1.
