Hello folks. - I'm a fan of old tools, I use them, but I'm not a collector. I got this in a tool box I bought recently and couldn't find anything about it. It seems to be from a mattress manufacturer in the late 19th century in Oneida, NY. I'm guessing it's for tightening a mattress frame or something like that. Anyway, if anyone has information let me know, also if anyone's interested in purchasing it let me know as well. - Best, Mark
