original airfoil data(DLBA186)
 

Dear Sir I want to have original data of DLBA186 airfoil. I think probably that original airfoil does't have some trailing edge thikness like as RAE2822 airfoil. Because original airfoil is a primitive version which isn't modified by Henne & Gregg. Therefore, it has zero trailing edge thickness with sharp closed. Please tell me, where can get information about it. thank you.
