I cannot add any information to the debate.
However, I am interested in it as own some U&U photos from Conlon that clearly have U&U reference numbers stamped on them, stamped U&U on the back and have been certified by PSA as "type 1".
I've come across some photos in my small collection that are PSA-certified as Type 1 which clearly aren't (for example, a John McGraw photos labelled as from the 1920s which was actually printed in the late 1940s) so interested to understand more.
Should add also that, without any equivocation, I am a bidder in the current Henry Yee auction. In fact, any price I was going to pay on the items I am interested in has increased due to frustrations over this past weekend .... i.e. I flew in from London to NYC on Saturday to see the Yankees vs Blue Jays game on Sunday that was rained off.
