MikeTheEngineer...I'm sure you've read many of dik's posts. If he asks a question, it is after he has exhausted every resource he has at his disposal. He's not a newbie...he's "old school" as am I, so we are used to getting things done for ourselves as are you...but occasionally, we run into walls...we will then beat our heads against the wall for a while, but eventually will ask for assistance to knock the wall down! We have awfully hard heads and tend to beat down most walls, but occasionally....
dik...sorry, but can't help. I have run into similar in the past couple of years with defunct PEMB fabricators. Check corporate ownership streams if available as many of these were absorbed by others over the years. I have one from the 60's I'm currently chasing.
