Sea Ghost. Based on the rod they are on, a Sabre made out of southern California, they are most likely AFTCO. Sabre exclusively used AFTCO roller guides in the 1970s through the 1990s. I am not sure after that. These are "early" guides as the guide from the mid-1980s through 90s had curved bodies.
Another company by the name of Varmac also used to make roller guide, reel seats, but caps, etc back in this time.
Sea Ghost, with any amount of luck I should have your answer sometime Monday

"They are very early AFTCO guides" is the answer I got from the source. Never thought to ask about year and I think they assumed I knew. I remember seeing them in the early 70's on factory-built Rock Cod poles when fishing deep water in the winter months was the norm. Terry could probably age them more closely.
