Here's a Wade Wingfield and Rowbotham which unfortunately has been drilled 30 degrees off (yeah, I know must've been an irish immigrant or something....)






And hhat about the deep pitting on the tang too - sand flush making for much narrower tang, or just somehow get into the pits, may be chemically (I really don't mind black pits on this over 160 old boy).

Methinks redrill the hole to be straight, fill in glen style with nested brass tubes and put back the ivory...
