For this lens 2 product codes are available: an L200F1.4 [a.k.a. Cat200] and an L200F1.4-E [a.k.a. Cat200-EOS]. The ...-E thing was dedicated to Canon EOS and kinda looks like a package name. If so, the L200F1.4 should be the FLA part of an AstroScope with a lens being integrated and the L200F1.4-E should be a set of FLA as described and a Back Body Adapter (BBA) for Canon EOS.
This lens is extremely rare. A tripod collar was available or even included. The exact aperture was F1.35 (hence this lens was sometimes called 200mm F1.3.
