I have several questions about the codes stamped on the barrel of my Remington 12 gauge SxS Model 1900:

1. What do the letters "LKEDY" signify? I thought I once read that "K" was the model number(?) and that "E" meant ejectors(?).

2. Serial number is 3902XX. Does this identify the year of manufacture?

3. I once read that the chokes were specified by a number code representing the number of pellets in a 30" circle at 30 yards. Is this true? Mine has "53" under the right barrel, and "41" under the left barrel. If the previous sentence is correct, what size shot was used to arrive at these numbers? My measurements suggest chokes are SKEET and IMPROVED CYLINDER.
(Since this gun was made before skeet was invented, perhaps there is a better designation - OPEN?)

4. Barrels are Damascus; I think it is called "star & horseshoe" pattern. Is that proper nomenclature for Remington?

5. Apart from the serial number, the number 3932 is stamped into the water table, barrel flat, and forend metal. Anyone know what this represents?

Thanks for sharing your wisdom....
