Your inclusion of a reference to Steve Hopf GG was timely. I did not have a good source. I have a number of cameras that need new GG and will certainly give him an order.

And, 20 minutes ago I got a lead on a Deardorff 5x7 at 3:00 am, the Internet never sleeps. I have yet to own one and this one is either fake or old, I will have a new learning curve. I shot Pentax H3 most of my life and now I am just getting into LF. I sure wish I had started earlier. Cameras keep me busy and safer than my old passion of motorcycle restoration. How did I end up with three 5 x 7 enlargers...Oh, nobody wants them.

Thanks for your advice and C-1 story, as a life long collector, I do chase the wind.
