Have downloaded the picture you gave....It is an interesting block....looks like they melded two together as the wedding ring shape is very apparent and yet it is squared with the other one...Cool will keep looking....Another thing you can do is trace the block...and then use graph paper or EQ5/6 if you have either and create pattern and templates from there...Maybe Patrice could assist you....if so...would be interested in copy of pattern. Also check Library for books about patterns of that time.
PS...I think I have some of those fabrics. :lol:
