Help attribute 1938-D/S buffalo nickel

I have a 1938-D buffalo nickel with an obvious D/S mint mark. I'm trying to attribute the exact variety. I'm pretty sure it's an FS-511. What do you think? The attached photo was taken with my little digital microscope.

Hard to tell. Do you have a Loupe and cell phone . I have a trick . Here's what it should look like .

 

Definitely looks like D/S, but the field is muddied.

 

There is no doubt that it is a FS-511. One of the first things I do is check the MM position if two resemble each other. The OMM-001 does not have any competitors though.

May we see a full image of both sides?

 

Looks like a clear FS-511 to me based on what I see at Variety Vista
