Robart #307 Hinge Dimensions?
 

I'm working up drawings for a .40 size aircraft and am considering Robart hinge points. There is a bunch of information on how to install them and so on, I can't find any information on the dimensions. In can infer the diameter of the barbed portion but I can't find the length of the barb nor the distance from the pin to the start of the barb. Can anyone provide me with this information or point me to where I can find it? Thanks in advance.
