Kerry,
It was definitely one of the older ones, single coated and made in the late 1970s. I owned a 180mm version of the older lens and I am fairly certain it would cover 80 degrees, but the 360mm specimen definitely did not cover that much. I figure it was more like 75-77 degrees because it takes about 79 degrees to cover the 12X20 format and the one I had definitely missed. I thought I read somewhere that the longer versions of this lens, i.e. 360mm and 480mm, had slightly less coverage in degrees than the shorter ones, but I can not find the referene.
