Contemporary (older) with "Cede Nullis" on barrel

[AZshot]

I saw this .45 caliber rifle at a show today.  Not knowing Latin, I thought it was signed by the maker.  Now I know "Cede Nullis" is just a phrase.  And I didn't get better photos because I thought finding the maker would be easy once I got home.  Do the poor angles identify the maker to anyone?  It was well made, incised carving in places, relief carving too on the butt, engraved trigger guard and a few other places on brass.  There is an indian head carved in the wood forend flowing from the front to the trigger guard.  Again, I wish I took better pictures, but I was interested in it.

It is Latin for "Yield to none."

Thanks, I had figured that out when  I got home to a computer.  Still no idea of who or when it was made, but I think the $1200 asking price is too high for me.
