Vintage US Divers parts/repair manuals?

[tm530]

Hi, I'm looking for a good quality scanned or copied vintage US Divers parts/repair manual/schematic for the Conshelf XII (12) and the K valve in the pic below. I know the XII is basically just a XIV without the 3rd LP port, but I'm still looking for the schematic. If anyone can help me out, I'd really appreciate it. I'm certainly willing to look through my books to find something you might be looking for!

Thanks in advance!
Tom
