A friend of mine is evaluating a booklet collection for a widow whose husband recently passed away. He came across a few BK240 which have the panes attached facing each of the inside booklet covers. Since BK240 was issued after the last McCann Booklet catalogue and Unitrade does not list a variety, he asked if I could confirm which pane orientation is correct and which is a possible variety.
Since I only have a single BK240b, I can only confirm that mine has the pane facing the upside down order form page same as his top photo.
Does anyone know which is the proper orientation and is the other one an unknown/known variety that should be listed as such?
