Hey, cap,
Do you have a copy of Hans Moust's book ("The Guild Guitar Book")? If not, you must get one.
He covers this period of the company's history. A few of the top Guild supervisors from Hoboken made the transition to Westerly to get the plant working efficiently and ramp up production levels. This was around 1969. It's a great read, by the way, and horribly tragic with Al Dronge's death shortly after the move (if I recall right).
West may be right about the numbers, but quite a few different models were already in the Guild line-up before the transition to Westerly. There was apparently tremendous creativity in the Hoboken and NY years.
