A modification to the H-501 Pencil Hardness Gage

Because the white plastic can make it difficult to see the milled numbers for the leadholders, I have begun coloring the numbers. The one is red and the rest are blue, to make them easier to see quickly. cleaned-3

I have also upgraded the lead holders again as a few customers had difficulty with the thinnest leads sliding back into the holder.
