A friend has a 12 gauge double barrel shotgun with the center rib marked J. SAIVE ARMS LEIGE and Le National marked at the breech of the left barrel with serial number 40314. MADE IN BELGIUM marked on the under side of the left barrel near the breech.

Barrels measure 28 / 72 centimeters and are choked Modified and Full. Dull finished half pistol grip stock measures 14 LOP x 1 DAC x 2 DAH to a hard rubber butt plate. Side clips and cross bolt locking, push button fore end release, European style sling swivels on the stock and barrels and two triggers. About 70% case colors, 95% blue, perfect bores. No dents, cracks, splits or pitting. Various markings on the water table and barrel flats. Gun weighs 6 pounds.

Any thoughts on who made it and when? What's a realistic value of the gun?

Thanks for any info.

Jolly
