The sales approach from Congo is rather laid back and relaxed, no push, no real marketing. The website is hardly ever updated. The News page is still 1997 !!!! OK other pages are 2004 or 2005.
Congo are a sleeper. They could play a very valuable role in LF photography, making the lens types no longer made by other larger companies.
Suggestions would be:
Wide Angle Protars, the Ross & Zeiss Patents lapsed years ago, it would be wonderful to be able to buy a small multi-coated modern version.
Hypergon's, the Goerz wide angle with the propeller, again a MC version.
Dagor's, it's unlikely Schneider will make them again
