I don’t see many Centennial Model 120A reels come up for sale. And when I do, they usually have the red front cover. I recently acquired a 120A with a couple of green front covers. One was a Century 100B cover that had been put on the reel that I know is incorrect but it also came with a plainer green front cover. So I started doing some research looking at the posted catalogs. I know the catalog pictures can be misleading but those and the descriptions contained within them as well as a few 120A owner and marketing documents I have are all I can go by when researching reels. The 1959 catalog appears to show the reel with a black cover with the ribs around it similar to the black covers on the previous model 120 reels. A 1962 owner document for a Model 120A also shows a picture of that black cover on the reel as does the schematics contained in the document. By reading the 1966 catalog we know that Johnson introduced that year the 120A reel with “black gear cases and Mohave Red front covers” as described in the 1966 catalog. It also appears to have a white button. Then in reading the 1965 catalog a year earlier, they describe the 120A reel as having an “anodized aluminum cover” but do not mention what color it is. The picture in the 1965 catalog also seems to indicate the reel has a black button, seems to have a black gear case frame, and has a cover that in appearance including the drain slot positions (without knowing the color) that matches the green front cover (which is anodized) that came with my black button 120A reel. So my red cover 120A matches the 1966 catalog and I am thinking my green cover 120A matches the 1965 catalog. So it appears to me that the 120A first came out with a green gear case frame and black cover and button (which Dennis (Huckster37) has and sent to me a picture of his), then for a brief period was a black gear case frame with a black button and a green cover, and finally a black gear case frame white button version with the red cover. Three 120A versions! As a follow-up, Dennis looked on eBay and found a couple more black frame, green cover, black button reels that look like mine that had previously been listed so that kind of confirms the green cover Centennial reel existence. I also noticed on this green cover reel the rotor pin pickup was different for this pick up configuration then I normally see. Usually the actual pin mounted in the nylon holder is metal. On this reel it is ceramic. So I looked at a few other reels and see that this same ceramic pin arrangement is on my Gull 122 reel also. Also the green gear case frame 120A has a rough finish, the black gear case frame green cover 120A also has a rough finish on the gear case frame but the 120A red cover black gear case frame is smooth. I just acquired a 120A green frame black cover and will add a picture of that after it arrives. The reels in the attached pics certainly have been used but are fully functional. Eventually I will get around to cleaning them up a bit! Fun stuff!
