Nice find Eric and great price too,looks like the original bag,I worked at a Kirby dealer back then,I was only 14,I did all the repairs,I remember the Omegas,Classic Threes and Heritage models fresh out of the box,If I remember right the Omega had kind of little rubbery textured dots on the bag,the Classic Omega looks a lot like the Classic One but the attachments that fit on the front of the machine are not interchangable,they changed the front safety switch on the Omega,so Classic Three attachments would work but they would be red of course,I found two packs of type H Eureka bags if you still need them,I pick up vintage vacuum bags all the time anyway,even if I don't have the machine,you never know,so if you want them let me know.
