    Harri,

    sorry, I refer to this.

    Francis

    Harri,

    I’ve been looking at the Verniers on the SI model and the incomplete diagrams in Luykx.

    The A Vernier is on the outer side, the X Vernier on the inner side to ensure it meets up against the correct scale?

    The B Vernier on the Luykx is on the inside, so presumably the Y Vernier (not shown, we need a photo of that side from SI) is on the outside?

    If we got the inside/outside positions correct, maybe I could add the white background with good old fashioned typex white paint?

    Might as well get it exactly right before I start on the next version?

    Thanks for everything

    Francis
