OK so we know it is not a 2610. It is either a 2360, 2460 (which are the same thing, except for pump tuning) or a 2510 with the larger displacement engine. Only problem is, I don't know how to break it down further. They all look exactly alike. Obviously decals on both sides of the hood are missing. Perhaps contact Long tractor parts and see what you can learn from them.
