Turns out I seem to be collecting C8's without wanting to. Here are three C8's; One from early 1974, one from sometime in 1978 or 79 at the lateset and one from
about 1997 or so. The Sandcast 1974 I bought about 6 years ago and it had good optics and those wonderful mechanicals of a sandcast. The 1978 was a rescue scope. Badly damaged coatings required a recoat. after recoating and careful reassembly it delivers nice bright images and has surprisingly good optics. The black one was donated to our club by a former member and it will be used for outreach. That one isn't mine so technically I only have two. Took the black one for a test flight and it performed well and is in pristine condition.
