You haven't given us much to work with. Need a name or model number.I'm sure you canfind original catalog info on the bowunder the Pearson logo at
www.archeryarchives.com
The site has catalog info running way back into the 30's but I don't think Pearson made a takedown before 1960. If it has a 3 digit model number, the bow was made before 1968. If it has a 4-digit number, it was made in '68 or later.
Pearsons don't have anywhere near the collector interest or popularity of Bear and Black Widow, but they made good, dependable bows. They are great bows for someone looking for a bargain.
