I see only one rifle. It appears to be a butchered up old military rifle, maybe a French Model 1907 or one of the musketoons with the same action. Any markings would help, but I think I can safely say that the value is pretty low. If it is French, the original caliber was 8mm Lebel, which was once made here but is now completely obsolete and ammuntion is available only at collector prices. Assuming it didn't belong to Pershing or Patton (with documentation), the value would be nominal, around $50 if anyone would want it at all.
