Picked up my Army & Navy Steyr 6.5 x 53 R and would like some help with the numbers on the gun. There is 40127 engraved on the trigger guard which I thought would be done by Army & Navy. There is 9992 stamped on the barrel and in front of the magazine. This has a B stamped between the 99 and the 92. Does this mean the rifle was by Gibbs ? Then there is a 109 stamped on both the barrel and receiver which I Thought may have been the original Steyr stampings. There are photos below and I would appreciate any information anyone can give me.
