VOC hanger advice

[mariusgmioc]

The corrosion is quite deep but uniform and consistent with its age.
The stamp is crisp but it is also corroded consistent with the rest of the blade so I am pretty sure it is original and not a later addition. Also the marking shape and style are correct confirming they are the original.

I am not very knowledgeable in tackling this type of corrosion but I would only clean it with bronze brushes & steel wool and WD40 to remove the active rust.
