The Dwyer masthead definitely did not fit the older (Jerry-supplied) non-Dwyer mast section of a 1984 M-15 I worked on. I do not think it would fit my 1991 vintage M-15 either. I would suspect that the same might be true of the older non-Dwyer M17 mast sections. I bet Jerry would know for sure.

Anybody: Would the Dwyer masthead currently used by Nor'Sea for the new Montys fit the old mast?
