Lynx, your A-5 was produced in the years of the Second World War while Remington had the contract to produce them.The troubling thing to me is the serial number you listed goes to high according to this listing."AMERICAN BROWNING" AUTO-5 - 12, 16, or 20 ga., Remington-produced model of the Auto-5, very similar to the Remington Model 11, except with Browning logo, mag. cut-off, and different engraving, over 38,000 mfg. in 12 ga. (ser. no. range B5000- B43129), over 14,000 in 16 ga. (ser. no. range A5000-A19450), and 11,000 in 20 ga. (ser. no. range C5000- C16152), stocks have Remington style round knob pistol grip. Mfg. 1940-49. Grading 100% 98% 95% 90% 80% 70% 60% $495 $395 $350 $325 $295 $250 $225 Add 10% for vent. rib and/or 20 ga. An easy way to identify this configuration is to look for the "A", "B", or "C" prefix on the left side of receiver. And of course Brownings site gives different serialization numbers www.browning.com/services.../auto5.htm But the A B & C does denote "American" A-5
