john deere #7 backhoe operators manual help

[dets jd855]

Looking for a operators manual on ebay for a jd 7 backhoe only problem is seems like there's many issues with serial # breaks per alphabetical issue
I have a 1996 jd 7 serial # between m00007x155001-155000
Can someone shed some light on what issues manual I need to get
I assume the higher the letter on alphabet the newer the jd backhoe?
Thanks
