Well it doesn't and was hoping for someone to tell me what I should be looking for or hopefully have a spare for sale!
If anyone needs the above tin its up for sale.
Yes this is indeed the size used for the KLG L777 plug.
I have two KLG L777 plugs left now we are talking about them. One pretty nice the other quite rusty but both still sealed in their tin. I had 50 of them can you believe that?
