[Double Lab]

I just received my GHE back from Brian Dudley and I am super pleased with what he did. The barrels had some pitting, the checkering was worn and the Silvers pad was smooshed and rock hard. He did a remarkable job on the barrels, recut the checkering and cleaned/refreshened the finish to where it does'nt look totally redone and still retains most of the patina in the wood. Truly a craftsman. One question I have is a stamping on the barrel flats (right) of a P.S. I'm sure it's been discussed but I never noticed it till now. Any ideas?
