Think i paid too much for a Fly Eye

[JoeG]

The early flat snap rings that held down the screens on the fly eyes were a pain to reach in a get off with the 2 holes at the end of the ring as was on mine. So JoeC, that would fit the timeline...Later on I stuck a easier to remove top wire ring with the pry openings on the top when they became available and just kept it for ease of servicing..........probably like you said after '70..
