Assumeing the gun is loaded I would guess the fireing pin is broken. It could also be that the bolt is not going full forward into the chamber.
It could be a dead battery.
It means your battery is dying
It depends on what's wrong with it.
wrong
You're doing it wrong, seven times.
Could be the Starter or the Transmission
I'm not sure if your trigger is new or if your serial number is wrong. The gold trigger wasn't produced until the late 50's once the Japanese produced the Brownings but your serial number would put your gun as being made somewhere between 1903 and 1939.
mostly likely something wrong with the sensor or gauge.
no way
It is in front of the radiator and the horn itself can be bad.
it might be a fuse
Could be temperature sensor Could be gauge
