Seeking Serial Number info for Remington Automatic Shotgun

[jandyford]

Hello! I'm a new member and I'm trying to determine when my Remington was made. The serial number is 10825X. The gun is a straight stock Auto-5. It has many of the early features as an early Browning Auto-5; square-profile recoil spring, 'suicide' safety, the afore-mentioned straight grip stock, early takedown hole in receiver, etc. The only place 'Remington Arms Co.' is found is on the barrel with the Browning patent dates. Any information is greatly appreciated.
