Your gun is a Grade 2 lifter action.
It does look to me to be a 12g. But only you can check it out and confirm.
Your serial number is not in the book.
Which means that there is likely not stock book records on your gun.
I did put your serial number into he PGCA research letter database page and it indicates that there IS records on your gun. Likely just order book records. But that means a research letter can be provided for your gun.

These early grade 2 guns with the sculpted bolsters are great!

8142 is probably the order number for your gun. You'll see when you get your PGCA letter if you ask the researcher for this information. He will not normally give you the order number, so ask. The 4 4 is the unstruck barrel weight, which pretty much means it is a 12 gauge gun. The D means Damascus barrels. I don't know what the 526 means, but someone here might. The U on the water table is the catalog grade of the gun. The U is normally a Zero grade gun, but the sculptured breech balls and Damascus barrels indicate a higher grade gun as a previous poster suggests. The water table marking is apparently a factory error. This is some great gun.
