The linear ones that I've used seem to go darkest held up to a monitor when the pip mark is about the 12 o'clock position. That's how I mark the CPL s that aren't marked and use that for reference. I try to mimic the old reference with the lever. You knew where you were just by feel.

Thanks for your comment. I learnt today that, out of 4 LCD monitors we've got at home, two have vertical polarisation, one horizontal and one emits light polarised at 45 degrees to the horizon. It might be a good idea to stick with the same monitor when marking unmarked filters
