Found this in a Loomis box, never seen one like it. Doesn't look or feel like a scratch. Whaddya think? Some kinda stain?
Looks like a stain, just weird I thought it may have been dipped in something, but no line on the reverse?
If anything I might say linear plating blister. but it would have to be raised for that. I still think it is a stain, it is just extremely strait.
