Kansas Creed,
I think it is great that you are restoring a Mistral that most of us would have ignored. It is easy to just buy a regulator which is already perfect, but by restoring one, as you have done, you are contributing to the preservation of vintage gear. Plus it's cheaper and a lot more fun.
The label looks good to me. If it were too good, it might not look authentic. What a great effort. I take it Bryan has been your mentor.
Thanks for showing it to us.
