Agree with the two-needle pine prognosis; if this was in the eastern US, you would have more-or-less Pinus nigra and Pinus sylvestris to choose between. And that would be easy, because Scots Pine has quite short needles compared to Austrian Pine's quite long needles.
In the PNW, you can probably grow a lot more species less often seen out here in the Ohio River valley region.
You could provide more images of the WHOLE plant, as well as some images of any stray cones around, the bark on new branches, older branches, and the trunk. Those can provide some positive ID qualities, too.
Additional 2-needle pines that are planted as ornamentals:
Pinus densiflora Japanese Red Pine
Pinus mugo Mugo Pine
Pinus resinosa Red Pine, Norway Pine
Pinus thunbergii Japanese Black Pine
Pinus virginiana Virginia Pine, Poverty Pine
Pinus pungens Table Mountain Pine
Pinus banksiana Jack Pine
