Bijou Double Barrel 12g sxs

Hi, looking to sell/swap/partial swap my 12g sxs. It's an old gun, probably someone's prized bird gun a long time ago. Works flawless, fires and ejects. Has very pretty scrollwork/engraving all over it. No idea about the choke. The inly identifying marks on it are BIJOU on the rib (see pictures) and I haven't been able to find anything online about it at all. 30.5" barrel. 

Ideally looking for a Savage 110/rem 700 in 22-250 or 3006. Would consider a 223/5.56 as well. Heavy/med barrel profile is a plus. Try me with your trades but I'm not really interested in Axis' or Axis 2s. Sussex area, thanks for your time.
