Melvyn...
I find this subject very interesting and I am in no waying trying to challenge you or say you are wrong. I would like to ask a few questions, perhaps play devils advocate, and perhaps try to make a case for Colt...but understand it is all in search of knowledge... and it is not designed to prove a preconceived point that I have. Does that make sense?
Here goes...
It is my understanding that Colt was the first to use blueprints and drawings. So, he could take these architectural layouts to his office or his home, draw on them, add in things, take them away, change this or that, and think about these types of things while not actually on the course. Wouldn't this make him the first true architect?
