This gun was made in 1953. the "x86914" is the serial number, the 1kg045 is a proofing mark. Value depends on condition and model (Is this is a Standard weight or a sweet 16?). Typically they can run anywhere from $400 to $1500+ depending on age and condition.
The value of your Browning BAR Mark II safari will be between 325-625 dollars,for a rifle exhibiting between 60%-90% of its original finish and a good bore.
Value is too difficult to be accurate without seeing the gun. Condition which includes the amount of original finish and original configuration will determine value. Recommend taking it to a gun shop for appraisal.Production numbers may be available through Browning
Agree with the model and year as a Mark II Safari from 1996, but seeing these sell for about twice that much in excellent or new condition. A check of completed sales on Gunbroker shows $800-$1100

No,not that I am aware of. Browning makes a Challenger mark III, but that is a .22 lr pistol. Browning also makes the Hi-Power which is chambered for 9mm Luger.
