I just inherited Gpa's old A5 and was wanting some info on it. It's a 16 with less than a box shot through it. The gun is in mint condition, still have the original 2 boxes of paper shells he bought. It has the suicide front safety and solid rib. serial number is x44242, could not figure out production date off of browning's website. Anybody have an idea on date of production and possible value?
