There was an article in the DGJ years ago about a gentleman gunsmith who took one apart and was amazed on the workings. He made the statement that these guns were made as well or better that an H&H which he stated would probably make people mad.
A gentleman that I knew (RIP) bought all the different models in 12 and 20 gauge. Some were quite rare and memory fails me but I think it was the engraving on the 20 gauge that no one at the time said existed. He also had them made to his specifications and had stocks made for his young to be inheritor (never married) for when the guns were turned over to him. At the time I think they went for $1500.
