Yes that is one of the early small square tail Manxes. They were made between November 65 and early Summer 66. I think there were only about 50 made. I sent an article to Anita about them that should be in the Fall Mania issue.  I only knew of four remaining and yours is now the fifth. I'll need to edit my article.

Where are you located?
