I acquired my V35 in about 1990; I think the camera shop saw the digital revolutiom coming, and let me have it (a demo model) for a mere £1200. I loved it, such a joy to use, but never felt that I was really getting Grades 0 to 5 as I was supposed to. When I retired in 2007 I acquired a Leitz 11c and a Durst DA900, both with Ilford Multigrade 500 heads, and boy, do they deliver the grades. And incidentally they cost a great deal less than £1200.
I don't know how the filtrations changed over the various incarnations of Multigrade papers. Back when I used fllters I had two or three sets as time went by, and one of them was labelled Multigrade 2; after that they were just Multigrade, so whether there was a filter set for MG 111 and another generation for MG 1V I don't know.
