It's a Boito, established in 1924, made in Brazil. The sole British distributor of them call them "the farmer's preferred choice", which for me being a Brit is just perfect. Will start another post with pics when the stock is replaced and I get it in my grubby little paws. My bro says it was made in the sixties or seventies, and the lockup is so tight, if you insert a shell and put a single sheet of paper behind it, it won't close. Hee hee. I can't wait.
