AMF Wing Archery “Swift Wing”

[Fishers]

I recently came across an old Swift Wing by AMF/Wing Archery, wondering if anyone knows how old it could be. The riser says only:

66"
SA-3000
AMO
48#

And that's all. Upper limb still has the retail store's sticker, Archery Center, 7701 Logan So, Minneapolis

Shoots really great and has pretty wood. I'm wondering if the "round" number for a serial number could signify anything special? Thanks, all.

AMF owned Wing from '72 to it's demise in '75 ....
....serial no. could just be coincidence
