It can be hard to post pictures here -- or sometimes just to post links
I think if you had a return after the link it would work better but I highlighted it and right clicked to open.
Welcome to the boards and hopefully someone can help out.
I would describe it as a Mayflower block with a square center.
Anyway -- I still haven't found my quilt reference books since my move and don't know off hand the name. I did find a similar block here, but it is flat and not on point like your center.
