"Discoverer" Model 6345, 90 mm (f15.6, 1400 mm focal length) Equatorial Refractor Telescope in the Sears, Roebuck 1970 Fall Winter Catalog.
Before the Sears, Roebuck and Co. was cursed with boneheaded executives in the 1990s, it was undeniably America's premier retailer, and just about everything available to the consumer market could be found in their bi-annual catalogs. A Sears catalog was found in nearly every American home. In the very early days you could buy a house from them in kit form, farm implements, tombstones, windmills, and even cars (the Sears Motor Car, aka Motor Buggy). Here is the entire 1912 Sears, Roebuck and Co. catalog; take a look at the index!
Beginning in the mid 1960s, Sears catalogs contained some pretty nice equatorial mount, refractor telescopes. The f15, 60 mm (2.3") "Discoverer" Model 6305 appeared in the 1967 catalog for $99.98, which in 2019 money is the equivalent of $763.49 (per the BLS CPI calculator). Then, in 1970 this f15.5, 90 mm (3.5") Model 6345 was offered for $499.95, or the equivalent of $3,401.88 (per the CPI calculator). Yow, I'm guessing not many of those were sold, especially as evidenced by the lack of available 6345 models that show up on astronomy forums and on eBay. Although not mentioned in the description, there appears to be a motor drive on the right ascension axis. Five oculars (0.975" ?) are included along with a special rotatable prism that holds all five - pretty convenient if it works well. Otherwise, it has the same set of accessories, but no mention of the really nice mahogany wood case earlier telescopes shipped in.
BTW, a good quality 90 mm equatorial mount refractor telescope can be purchased today for about $300.
If you happen to have a Sears Model 6345 telescopes and are willing to part with it for a reasonable price, please let me know.
