I was given a set of these, presumably for contrast control of VC papers?
I have numbers 1, 1.5, 2, 2.5, 3, 3.5 and 4
Can I assume this is a complete set (since the person who gave me these had 2 sets in the same range of 1-4), or am I missing .5, 4.5 and 5?
They are all 150mm x 150mm, and I was planning on cutting them down slightly for the Durst 1200 filter drawer.
