Yep, definitely a 180. The rear sight is unusual, most likely someone scavenged the original or lost it.
They're usually a good shooting rifle, on par with the 190, since the barreled action is essentially the same.
Does the 180 and the 190 use the same trigger? I'm under the impression they do, though I've seen both single- and two-stage triggers on the 190. The one I owned was a single-stage, the borrowed one I learned to shoot with was two-stage.
The 190s continue to fetch good prices on the EE, especially with the original sights. Between $400 and $700 depending on how proud the seller is.
When you consider the alternative is a new 64 Anschutz at $1500, that's not surprising.
The older rifles didn't have any of the 64 series' ejection problems, mercifully.
