Unknown astragalus(?)

I grew this a couple of years ago as Astragalus angustifolius, in order to compare to an old plant I have. It was soon obvious from the form that it wasn't Astragalus angustifolius at all. It's bloomed this year with rather attractive grey-purple flowers. Any idea what it might be?

So, it does appear to be an Astragalus, from the lack of a spur on the thingamabob...

And here are the large, inflated seed pods, about 1" long:
