I can't answer you question, but maybe you can answer mine... There's not a lot of seagull stuff in the USA. Some cheap medium format tlr's and paper and stuff. What else do they make? Is there a web site that shows all their line? Any importers? Many catalogs cary the $150 tlr's, but I've never seen the back you mention. Am I just overlooking it or is it not readily available in the US? What about other large format items???
