Something is up with the front suspension of my car.

After driving a long, cambered gravel corner, I hit a pothole on the ground. About 20m afterwards, as I ran off a curb and back on the road, I heard a reasonably loud bang from around the front left tire. I continued onwards slowly, swaying the car a bit too see if anything was wrong, but the car felt perfectly normal.
After carefully driving home (only a few miles) I measured the ride height of both front tires, and they were identical. As I shrugged, I noticed that the left front tire seemed a bit off. Went to the garage and got one of these:
(whatever they are called)
I measured the camber of both front tires, and the left one has a bit more negative camber than the right one

I jacked the car up to see what's what, and at a glance I didn't spot anything out of the ordinary. The front shocks are quite rusty, but everything seemed straight and true. Im going to take the car off our driveway and measure again to see if it's level or not, but my quess is that it's not a measuring error.
Anything like this sound familiar to you? You'd think that if something crucial had gone (for example a spring), the ride height would change, or the handling be compromised. Could a broken/bent shock absorber cause added negative camber to one of the front wheels? I'll have to replace the front shocks sometime anyway, but if anyone has had a similiar problem/has a quess at what could be wrong, please share your info..
