I'm a happy owner of hasselblad 503cx (year of production 1989). Bought it on ebay in mint condition. Looks that the attached screen is acute matte D type, because it has two little D shaped notches in the metal frame. It has microprism and split-image, so as far as I know it's number is 42215. I have second hand camera, my friend is the first owner of 501 model equipped in plain screen 42204. I find his screen much, much brighter than mine. My screen is hard to focus...
I do not think D type screens were available back in 1989, so looks that previous owner changed original non D type to D acute matte. Anyway, I suspect that the screen is a fake D type. Perhaps someone put old type screen glass to metal frame that comes from D type. Is it possible?
thanks for help.
