Paul,
This post might get a better response in the General Information section.
I am a user of cast iron first, love being on here learning about cast iron. I am not a collector of expensive pieces. Started working on full sets, now not so much.
I have had a few pieces repaired, my welder and most others think its crazy and it is not inexpensive.
I think I've repaired a piece so I could use it, but have more then enough other pieces that I seldom do.
I understand picking up a piece just to be able to hold it, see it first hand, increase my understanding of the progression of cast iron. The old gate marked skillets are so thinly cast and light weight. What are your Dutch ovens like?
