My kid just swapped positions to a conpany I'm mildly familiar with. He's gone from a mill maintenance crew chief/engineer to a different company as project management/design engineer.
He probably really wouldn't be using the book, but I was thinking of finding a copy of the Ladish Catalog 55. It would be a desk warmer/rare-ish decoration. I used one when I was a piping designer. The catalogs have become a rune stone, dead sea scroll for fittings.
Minty versions on eBay are listed for North of $300. My pockets aren't that deep.
There were a couple listed in my price range, but they'd need work. I called re: binding repair at a place about two hours away, spitballed a price at $280 sight unseen..... 8O
I was looking up how to fix it myself. I found this guy who is pretty creative and entertaining.
