Wow, I would have told the guy to go pound sand and shipped the razor back to him... I think giving the guy GD scales was generous, and frankly he should be grateful to have a talented resource like yourself working on a razor for him... I do this stuff for fun and relaxation... I have no time for that kind of attitude... I would have made a pair of scales from popsicle sticks before giving him a serviceable set - even if they are GD scales.
