so my dad just found a book of 3a sized negatives from his grandfather in 1913. I'd love be to print them up for the family but it just seems like the 5.5 inch length would be a stretch for my enlarger to cover. Do you guys think it's worth a shot to file a negative carrier out, or should I just contact print them? Either way, they'll be scanned, of course.
Rather than break out a file set, make a temporary carrier from black mat board and test to see, you negs are a little longer than 5-inch but also a bit narrower than 4" diagonal is 6.38 inches and it should (maybe?) work, especially if you could live with a tiny bit of cropping on the long side. On the other hand you could just scan the negatives if you have the right scanner.
