Both the GodfreyandKnoll designs were 38%. Here's a link to my Godfey build www.rcuniverse.com/forum/m_9582545/anchors_9620353/mpage_2/key_/anchor/tm.htm#9620353,
if the parts look like these it's a Godfrey. If you have the plans what more do you need? Just start gluing sticks together and reducing the parts count in the box.</p>
