S&W Model 17-9 Masterpiece Compliance

[Netvine]

Hello,
I’m buying a model 17-9 Masterpiece Smith Wesson. I notice that the compliance list has 150477. but on the listings I just see 150477. Do they go by the model number and SKU, or will any 17-9 do?
Any help would be greatly appreciated.
Thank You
Merry Christmas!

Addition info.
The Roster specifies 150477A. The revolver must have a letter A engrave under the top strap, the Roster also specifies the picture of the engrave A/B model letter . Not just any 150477 approve on the Roster, I was once want to buy online a S&W 17, but the seller said he did not see the letter A engrave so I did not buy it. But the Roster regulation may change now.

"Smith & Wesson revolvers currently on the roster with the letter ‘A’ after the product code, will be engraved with the letter ‘A’ on the underside of the top strap of the revolver."
