I believe this stamp has one line recut in both lower triangles.
This is found in only two plate positions. 32R3 and 95R3 according to the USPCS site.
My stamp wants to be 32R3. I can't say for certain, it's a match for the images available to me online.
Plate 3 was used to print a lot of stamps, so maybe I'm seeing differences *edit* - due to plate wear.
