A dimension for locating the launch lug first shows up in revision C of the instructions - which is the version that introduced die cut fins, approximately 1980. The dimension given is 1 3/4 inches from the bottom of the body tube to the bottom of the launch lug.
This is the dimension I use when I clone earlier versions of the Alpha...as it certainly matches the description in the earlier versions of the instructions and it looks about right.
