How to find info on a Sears VCR

[ESigma25]

I picked up a Sears "top loader" VCR, in quite nice condition for its age, but due to Sears' byzantine model numbering system I have no idea when it was made, who made it, or how to find a service manual for it. The model number given on the machine is "934. 53131350" which I can't imagine will give me much of a result if I try and Google for it, is there some way I can decode this to get actually useful info?
