The scratch marks are actually streaks caused by over-inking of the stamp and then something brushing the surface of the still-wet stamp.
I take back what I said. These are plate scatches which caught and held the ink as it was applied to the stamp.
A double transfer is when the roller die which presses the stamp design into the plate is applied twice to the same stamp image on the plate, usually to only a part of a the stamp design, but in rare instances to the whole design. A double transfer doubles the existing design and does not introduce new design elements. These are scratches with no indication of doubling of the existing design element.
An examination of the edges of the name Webster and all engraved lines surrounding it are not doubled and in fact are as clear as they were designed to be (for an over-inked stamp).
This is an example of the effect that applying the roller die twice to the design. It creates a doubling of part of the design of the stamp.
David.. maybe I'm missing it on this one.
But I'm definitely not seeing the transfer lines on this one?
I see the 'scratch' marks in the letters, but I'm not sure those are transfer lines?
Some of the others you posted were a bit more obvious, but this one I'm not so sure of?
