Rick, For never being restored, it looks like it's in good shape. I see you have what looks like the original lights! They are hard to find. I haven't found a repo set that is exactly the same. I really think the term Jubilee is used loosely, as only the 1953 and 54 were true Jubilees. The rest were just look a likes. Now that's just my personal opinion. It's like the older Fords were all called red belly's, no matter what model it was as long as the engine was painted red. Terminology, just terminology. My brother in law has an 800. Looks just like ours but it has a two position clutch. First position disengages the transmission, second position disengages the PTO, where our PTO's are in any time the clutch is out and the lever is engaged. Bad feature about that is bush hogging and coming up to an obstacle such as a fence etc. You push in the clutch and the centrifugal force of the spinning blades will push you right through the fence. Gee, I wonder how I know that! Nothing like first hand experience to embed a dumb maneuver in the brain. After that episode, I bought an overrun attachment. Worked great.
Oh, I forgot, My PTO shaft is the larger one, pretty much standard one for today on smaller tractors. I think 1954 was the last year for the small shaft.
