Old Centuri Parachute Instructions

From the older Centuri Black Widow instructions I found these parachute instructions.

I knew Estes sold parachute material in square sheets but didn't know Centuri supplied square sheets in their kits. Centuri shows you how to fold and cut the square into a hexagon.

This is the earliest I've seen where shroud lines are attached side by side in a long loop. Estes was still having you cutting and tying six separate shroud lines into the early 1970s.
