Yeah, its interesting to consider that the Terrus and Parrus are basically Walthers low end rifles.
I just spoke with a tuner who pointed that out to me and doesn't work on them, but recommends the other Walther rifles. The LGVs & LGUs must really be something.
I don't know what the Parrus looks like inside, but despite the low price mine just doesn't feel cheap when you use it.
Smooth to cock, nice shot cycle, accurate.
I'd love to try working one up to see what kind of honest performance they can deliver with an upgraded spring, seal and tune.... Could perform like a low end PCP.
