for those that responded with not one clue.. me included.... https://www.sheldonbrown.com/retrora...h-alyeska.html

the bike is well worth an bit of investment... and it's certainly no Box Store Special.

The stock rear hub is a QR'd Sansin RE-50... if that is no longer on the bike, then we all needed even more info, but some chose to attack box store bikes instead.

personally, i assumed it was a solid, nutted axle...

my apologies to Abdon.. and thank you for saving a cool old touring bike!
