Thanks for the info - my first thought is if it has a pin hole then it's thin in the area which means it could be thin in other areas. I know it's a 40+ year old part but as you can see above in the string there are pieces out there that are better preserved - I just can't spend that kind of $. It's sounding like yours may be slightly better than mine but I'll pass at the moment. Thanks for the response and if anyone else is interested they can contact you.
