I used to have a dash-0 but no longer. Quite a nose heavy gun accented by the round butt ,full under lug and un-fluted cyl. Square butt conversion grips helped but I never fully bonded.
But those are just my weird parameters and do not discount your gun.

Yours has some odd points. Not common but I have seen a few of them , but never the lasered engraving on the side. The serial prefix would indicate a much later shipping date ,possibly as late as 1994. All that and the double stamped model number MIGHT indicate a out of sequence assembly of left over parts clearanced by one of the distributers.
I am seldom an advocate for getting a letter but if the answers are important to you , it may be your only recourse.
