i thought it was 1973, due to the model name, but i may have jumped to conclusions - the numbers appar to be chronological across the entire brand, so this is the 1032nd takeharu guitar ever made, and it may be closer to 1971 or 1970, given that they seem to have made around 1000 per year.
there only appear to have been 9000 or so of these guitars ever made - total, all models.
