SL, how big do you reckon the spiral would have been? I ask, because there appears to be hardly any curvature in the grooving, so it must have been quite large.

Cheers

Hi Eds,

SLs response to my post seems to have disappeared. I read it 1st thing this morning & can’t recall anything controversial.

If I remember correctly, it mentioned an email of congrats from Manch Uni & a view the carving may have been rectangular rather than spiral.

Just interested.
