If the pin is 3/8-10...actually Meucci has a more consistant pin size and collar size than a McDermott. The diameter of the older McDermott Collars are all so different.
I have McDermotts going all the way back to 1975 (first production year) and up into the 90's, and their shafts all interchange perfectly, pins and diameters are exactly the same and they screw on straight.
Meucci has been far from consistent in this matter.
