It's an Astle cue I believe.

The lead isn't even a thread, if you look hard the major (and minor) sections are straight, no pitch.

Only recently discovered my Gulassy sledgehammer has a modified 3/8 10 that if measured is neither 3/8 or 10
I like Fatboys naming of such

Its a neat looking pin although I don't know how much good that does you, you cant see it when the cue is assembled.
