The P in front of a 100,000 series serial number denotes the gun is a model 1894 (vs. a model 1900). The P and Q in front of model 1900 serial numbers was an inventory symbol.
Nobody knows what the barrels stampings such as LAEY stand for. That is is lost in time.
It appears you know the gun is as A grade from the subject of your post, the letter A should be stamped on the watertable. You mention your gun has an orginal p/g cap. That strikes me odd, most 1894 A grades came with they called a half pistol grip which is similiar to a Prince of Whale grip, a rounded wood knob with no cap.
Your factory pattern results should be stamped on the barrel lug, the first number is a implied 3. 12 gauge guns were patterned with 1 1/4 ounce of 8, 511 pellets if memory serves.
The Remington doubles are good guns, I have two 1894 10ga guns and 12ga 1900 KE.
Thanks- the buttstock is a replacement, good dims and the top spur (aka- widow's peak) Rem/UMC logo embossed- and correct period screws- also the floor plate screws are unmolested.. You are right, Sir. The late Edmund Osthaus owned and shot two 12 bore Remington ejector doubleguns.
