Neat stuff for sure.

My dad grew up in a special place of privilege where his early childhood education in etiquette and the history and nature of fine guns combined with whatever charm he was able to bring to the conversation got him welcome access to the stock of Fine Guns at Abercrombie and Fitch and SF Gun Exchange from when he was a youngster on.
He had encyclopedic knowledge and deep appreciation for the gunmaker's art.

Of everything he'd known and seen and handled, the icing on his cake would have been a 2" 12b best Brit boxlock.

The world of boxlock has such vast possibility for potential and creativity. The gun shown above is a great example. An integral feature of it's architecture is the ability for it to take care of itself!

If I were thinking of doing a soup-to-nuts scratchbuilt field gun, I don't think I'd be able to keep myself from pirating the design notions of this tidy lightweight Nimrod.
What a simple and elegant design, what a cool feature of a 'take-along' spring vise!

My thanks in the hat to BH50 for sharing his nice lightweight 16b field gun...
