Grizzly,

Yes that rifle, the 470 boxlock, labelled "Griffin and Howell" is a Thys. If Thys's name were on the rifle it would have a bit more here and there, especially where you can't see, and be priced a bit higher too.

I have handled that rifle and its nice. It is relatively light or at least feels that way IIRC, and is well balanced.
