That’s a pretty good guess, considering how much of it was in the photo - you clearly know your stuff! It’s even chambered in a nod to you lot, in .30-06, which works very well on the deer we have here (reds, fallow, Sika, roe mainly). Love the Mauser action with the flag safety. Nice Sika with an abnormal set of antlers here too (extra tangs on one side).

I almost stopped at Rigby when I was in London last week... Almost. Next trip!
