could anybody help me identify this beautiful old telescope. i rebuilt it and there are no markings on it except for the pyrex stamp on the main eight inch mirror, and the small bodine motor that drive the main arm. it is really put together well and weighs four hundred pounds. the main drive gear is brass, setting circles are aluminum. any help would be greatly appreciated. original color was drab green. tube is welded steel. finder scope has cross hatches etched into the eyepiece.
