I'm told that the Oxford model does actually come with the correct style of buffers, it's just that they are included inside the box & hence need swapping over, strange that they didn't fit the correct pattern in the first place, unless of course Oxford have a photo of the wagon in later life with oval buffers fitted. I personally went for the Hattons version, preferring their shade of green & no over scale chains. other than that, I don't think that's there's any difference between the two versions.
