Another stab in the dark trying to add another spoke in the SEA hub.
An old NWA routing east-west (MSP-BIL-(? BZN-BTM-MSO-GEG ?)SEA) flown with L188 eq (Electra) and then 727-100
And an old WAL routing north-south (Calgary-Great Falls-Billings-Sheridan-Casper-Cheyenne-Denver) DC6B and L188
And another old WAL routing east-west (MSP-BIL-SEA) 720B
Aircraft equipment and cities not really certain of - but a WAG recollection !
