So I was going through some stamps and found these 2 marked on the back - rouletted or "roul" I'm guessing... Thoughts - yes/no? I clearly see on one of the stamps the edges were cut (im guessing) on 2 sides. The other seems to be jagged edged on all 2 sides.
Also, guess as to what the number is in the diamond cancel?
The righthand stamp appears rouletted on its righthand side, although that may also be clumsy handling of a scissor. As you wrote already, the top and lefthand side of that same stamp have been cut. There is no way rouletted stamps are cut on some sides.
As for the second stamp, that looks rather like someone tore of the stamp.
The Archer rouletting is quite pronounced (wavier). Also, it is unlikely they were ever used. These come from plates 70 and 71.
I am a novice. I see maybe a few marks that could be rouletted, but the stamps are in poor shape. I am not even sure if they were rouletted if they fall into the correct time period or Alphabet range. I am just trying to learn the alphabets. Here is the wmk from one of them. I cannot see the other clearly.
