I need help finding the value of RUGER 22 cal MARK 1

the mark I ruger 22 pistol was made in different models ,,for a standard 4+3/4 " barrel with a black or silver eagle medallion on the grips.. value would be 150-275,,if the grips have a red eagle and are authenic red eagle grips to the correct pistol values would be doubled depending on condition,,but for red eagle grip models you gotta know if it's original to the gun or someone has changed them,,there were around 26000 mk1's made with these grips prior to 1951,,
