Ben Pearson Rogue

[Migra Bill]

Hey guys- just picked up a BEAUTY Ben Pearson Rogue. It is a Rogue 7058 AMO of 58" 45# @28. I went to ArcheryArchives.com and it shows that the Rogue was made with a 58" AMO in 1975, 76, and 77. My question is this- Any way to tell which year the bow is? The serial number is 107410-471. I can;t find a sight that will tell me the year based on serial numbers. Any clues?

Thanx
