Ah I see it's an SMK XS36.
Isn't that the Chinese TX200 copy? Kind of looks a bit like one.

My first rifle of recent years was their Custom Lion and despite it's many detractors I found it a very useful and accurate gun, once I'd put a decent scope on it. It gave out around 11.5 ft/lb with its original spring so I see little need to upgrade if it's as good as mine.
