MID ENGINE TRIKE FRAME DRAWINGS

This is a drawing of a mid-engine trike frame.  This is all the information I have on it so don't ask for any more.  This was sent to me asking for more information.  We think it was a Co-Trike frame but can't find any information concerning Co-Trike.  I am posting this because a lot of people wanted to have it.
