Type 64 Sleeve, with holes not found in 55
Notice the holes at the end of the sleeve (click on the image to enlarge it). These holes normally look black because you are seeing the back of the negative, which has a black mask on it. In this scan, the negative has been removed. Type 55 has none of this type of hole in the sleeve. It can't, because the negative lacks the mask.
But what are these holes for? To let air escape/enter as you move the sleeve over the captive negative?
If you can put a half dozen holes behind a masked negative, I'd assume you could put many more, which would be handy if you needed to immerse this in water and flood the sleeve.
