Imperial proofs

The deeper step, rearward of the #27 is noted as being larger than most...BUT NOT ALL.

I wonder at the possibility that Spandau may have ground down another toggle to put their name on it. I am going to have to get access to a precision micrometer and measure.

I cleaned out just the letter P, as gun oil and gun butter didn't seem to affect the white. Even tried using an electric toothbrush on it. No go... It finally softened enough to pick the white out with a needle......very carefully.

To my untrained eye, the letter appears stamped, not tooled.
Take a look and see what you think.
