Christine — Apologies for a completely irrelevant post and for wasting your time.
Nevertheless I have not asked the Moderators to remove it as some might find it useful in helping determine whether or not their piece was machine threaded or was made by a different technique, usually rib and twist, but, occasionally, other methods such as the Stuart pattern shown in Gulliver, bottom of p.121, which was either pick up rods and twist, which I prefer for this this particular pattern, or trail and twist.
