This was reffered to at the time of production to the different level of finish of the model 30 shotgun.The model 30 could be had in various levels of finish and engraving from grade A-thru grade D,with each level being more fancy as far as the grade of wood,and engraving of the metal.I believe the level G stood for the field grade model.

you need to know the letter in front of the number if there is no letter then it was made after 1969. the letters start with C which is 1946 D is 1947 E is1948 about 1965 the letter change to AA from that point i would need to know what the letter is hope this helps by the way a 336 marlin with the letter C or D is real rare
D prefix Marlin 1893's are always post WWI era. The Marlin company was sold to Rockwell Intl. during WWI, and after the War the company was resold to the Marlin Firearms Corporation. At that time serial numbers were restarted, and prefix letters added. These first post WWI guns were assembled from leftover pre-War parts, and so some 1893's with prefix letters are found after WWI. Your gun was most likely from around 1922-23 era. It may also have the "Marlin Firearms Corporation" rollstamp on the barrel.

I see a Marlin 36SC in The Blue Book of Gun Values. It states the "SC" reprents "Sporting Carbine" This is the 3rd Variation of this model and the gun was made in 1946. More info for this model...... the model number has a capital "A" in the suffix and a small case "c" in the prefix of the serial number. If it was made in 1947, it would have a capital D in the prefix of the serial #. I am no expert by any means, but I don't see any newer versions in the book with "SC" in the model number.
A marlin model 36 adl 3rd variation which should have a C or D prefix to the serial number is selling for between 450-550 dollars.If your rifle has a B prefix to the serial number,then it is a 2nd variation model 36 and is going for between 600-750 dollars in 90-95% condition.Which is what I would assume you mean by (mint).
