Thanks Papaw. I do see though that those were buggy tools. This is much later than that era. I doubt its older than the 50's but I do not really know. I tried searching the eberhard company on google and all I come up with is buggy tools as far as any tools they manufactured. They seem to still be in business, although owned by another company (Eastern), but manufacture hardware such as latches and handles for the defense industry. So I can't see the connection to this tool.
