Consequently, it would appear to be a 1973 model, though the frame itself may have been manufactured in late 1972.
Thanks for the clarification. If it would be useful for you, I could go by the shop again and see if I could get date codes off the cranks and (if they're present) the derailleurs. Let me know.
