>> my name is john and i live in springville, new york. this is a replica of the traveling forges that the artillery and calvary would have with them. the basic purpose is to repair items that break, such as handles, chains, also the ferry years would use the forge to re-shoe horses. i like to tell people that the job back here is somewhere to a nascar pit crew. we were the nascar pit crews of the 1860's. working with us would be carpenters that would repair the sides of the wagons. the wheel repairs, people who
