It is a Chinese made xs78 imported by SMK.
It take two 12gram bulbs and after some valve work and another more open transfer port seal it gives forty shots.
The trigger is fantastic with three adjustments, sear, over travel and weight.
In 22 and very accurate.
The only gripe was I had to bend the barrel a little to centre the rear sight. Not much though.
I've been looking at those, albeit in 4.5 mm and in the AR2078A variety. But the best quote I've had here would put one in my hands for almost twice retail in the US of A. That's a lot of money to drop on a Chinese pellet gun. Of course, my Air Arms ProSport cost quite a bit more - but it's not Chinese!
Looks like it's doing a good job for you.

Looks like Jess has grown quite a lot since you got her or is that just the perspective from the pictures?
No sir. Camera! I have felt more meat on a rabbit!

The 177 is slow and needs some work to get towards 750fps.
22 versions get up to 650 with some fiddling.
The other thing may not like is that the bolt cocks on closing!

Yes, indeed. I'm wavering between the QB and a Discovery, although now there's the Maximus in the mix, too - albeit not 'til mid May or so. The thing with the QB is that one can play with the cartridges (bulbs) until one gets the wherewithal to bulk it or HPA it. The Discovery (and Maximus) are both either bulk CO2 or HPA which entails at least an investment in a pump. Some folks report decent accuracy in the 12fpe range with the 10.5 pellets. I think it'd be a hoot to set up a QB for Field Target and give some of the local yahoos a run for their money.
The cock on closing isn't a grand thing, but there are work arounds for it. There is also a new thingamabob in town that they call an SSG that is supposed to help conserve gas (ie give more shots at the same power level). It's amazing the information out there on those QB rifles. Folks have been modding and hotrodding them now for some time.

I had a Disco a few years ago and they are a good efficient system and very tunable.
However I hated the fitting of the stock to me! And the reach to the trigger was long for my small hands!
