PS, yes your added pic shows the ROUND detachable 50 amp shore cord. BUT, your shore cord male end should have 4 pins.
It does have 4 pins you can't see the 4th less you know where to look.
On the 30 there are 3 blades. All in the circle.
On the 50 there are 3 blades in the circle and th 4th contact is on the OUTSIDE of the plug. It's a metal strip that connects with what looks like a ball bearing in the side of the inlet.
I see the poster figured it out. IT is about th4 7 O'Clock position in the photo.
