Looks like the name on the blade is A. Burkinshaw who founded the Burkinshaw Knife Company Pepperell Mass in 1850's but the hallmarks don't match what I researched so think this may have been made prior too him starting his company (?)
My research shows that he came over to US from Sheffield Eng. where he was workig as a cutler / knife maker
Pictures show the two marks > one looks like a 6 sisded star and the other either crecent moon or perhaps abbrevi. "Cl"
Any thoughts ?
