Probably lead pipe swages, when I started work as a maintaince fitter for a water company in the 1970s there were a few of them thrown under the bench in the workshop, long after lead pipe was discontinued.
I had some intricate porch supports made in 2.5 inch wood a few years ago, and they were cut entirely on a hugh band saw by a pattern maker at a local foundry. They had the right tool and a skilled man, it cost me very little.
