I think AL was so long in gestation, and was probably a plan B set up for if Ken said no to SA's offer, that it's very hard to say for sure 'this is where AL was established'.
Maybe the name was taken before as a plan B, but when was it first staffed with machinists, and were these first staff the ex-Aero deserters?
And did the website with designs go live only after the patterns were copied?
