I let you check for the hammer design
Must admit.. looking at the book, I realize they really did do some elegant hammer work.
really like that simi-flutted cylinder on your '51, that's a good look. I have a Pietta '61 with those half-flutes. That's my one concession to the counter-historic, cause they look so cool.
I love how it looks ...n im not a huge fan of fluted cylinders in general. I wish I could magically fill em on my blackhawks. But with my London 51 I have fantasized fluting a couple spares. When I bought the cylinder, I was thinking right away that since it was the oddball, it should be made into a conversion.
