What turret bearings are these?

So I found some of these turret bearings but I'm not sure if they're the light duty ones or heavy duty?
From what Ive been told, there are only 2 different styles. I have an OGPK, so I definitely need the HD one. Can anyone tell by the photo?

I asked they guy selling them, he has 3, but he said they under some tires and wasn't interested in moving them
