Here is a very old shaft I got with some 70's meucci cues, but its NOT a meucci (5/16 x 18) pin shaft. It almost fit my custom pierce cue w/ 3/8 x 10 cue, but it would only go on about 1/2 the way down. I did not want to force it. Any help would greatly be appreciated. Here are two pics of the shaft in question.
