I found this head in my ol mans shed last night along with a craftsman no.6 hand plane. He didn’t have any info on the head or where it came from but has been there a long time. The head is well worn. It has a hint of a phantom bevel and has some stamping I can’t quite make out. Looks like a letter c or possibly o. Then some pitting then the letters co. Then below that is a very faint stamp I believe says premium. The forging makes me believe it is older than any of my other heads. Here’s some pics any help would be appreciated.
