Daisy CO2 200 Daisy gas pistol

I came across a Daisy co2 200 semi auto gas pistol .
I was wondering if I could find out more information on it. How old it is and if has any vintage value. View attachment 549000View attachment 548995View attachment 548996View attachment 548997View attachment 548999View attachment 548998View attachment 549003

I know they were built as far back as the early 1970s, as I had one. Fun pistol, but the seals are prone to go out pretty quickly. I understand that reseal kits are available. Maybe Baker Airguns? I don't think they have a big following like the Crosmans. Saw one on another forum a few months ago for $50-60. But they probably go for a bit more in good, working condition.
