Even after all these photos, there's too much room for doubt to nail this one, which is why I didn't join this thread from the outset. However, my first thoughts were of alder, which I've turned loads of and still have plenty in stock. It certainly fits the general description of, "...light, easy to turn, no real smell".
If you know this to be a home-grown timber, then I think that alder is as good a guess as you're going to get, but if this was an imported timber, then the world is your oyster. A recent study at Bournemouth University placed 1575 different species on the list of commercially produced timbers and not even the wood database can describe that many.
