I don't remember when Pearson went to four digit model numbers, but lots of Pearson bows have the last digits of the model number as part of the serial number. The arrow through benpearson logo was used in the sixties. The BP H-number models were late '60s/early '70s
It's worth is whatever someone will pay for it, so who knows? Condition is a big part of the value, of course.
