Peter Ventreska had a dojo on Pearl St in Boston in the late 1960's. I studied with Peter for two summers: 1966 and 1967 while I was in College.
While I was there, Peter wrote a book “Shotokan, the Ultimate in Self Defense”. It is still available on Amazon. The book covers basics, Tekki Shodan, and Bassai Dai. ( I don’t believe he taught the opening of Bassai the way it is shown).
There are no links about him that I could find. Maybe I’ll stop by your dojo sometime, I have some interesting stories.
