    Brilliant work Bill,

    I've been rather ill (not Covid19) so haven't been able to do much. I built replicas of my perfect original years ago. I think many of the posts may still be lurking on Navlist archives. Let me know if you need measurements etc. Looks like you've got it anyway, by Jove you've got it. When I'm better I'll test it against the original.

    Best wishes,

    Stay safe.

    Francis
