It seems to be a double opposite wing that then splits as it ripens. The fine stalk is hidden until this happens and it is possible to see the matching groove at the end of the seed. You can visualise the two wings fitting back together but not at an angle.
The only key I can find is for the leaves, not the fruit, so I will have to keep checking.

Acer buergerianum

I have compared the fruit with Acer palmatum (which I have plenty of) and see that the 'individual stalks' are hidden inside pairs of seeds until they ripen and separate. Angle between seeds is close to 180 degrees, so not a V-shape.

@MichaelMulvaney, this is not A. buergerianum. I have added photo showing more clearly that fruit is on individual stalks and not joined V shaped samaras (or is this how they dry?). Seed is flat and wing shape is different.
