SA Collar Tabs Legit?

[CurtD]

How do these tabs look to everyone? They seem to be well-made. I am a bit concerned about the metal that is stuck between the leaves.

Reverse.

Thanks!

Personally, After 60+ Years, I Like To See Some Verdigris On The Device Pins Caused By A Chemical Reaction With The Chemical Elements Found In The Period Buckram, These Look Very Fresh And I Would Entertain Doubts On These Without A Hands On And A Proper R Z M Tag. These Appear To Be Unissued And Should Have A Properly Coded Tag For A Blank Tab.

Thanks Bob for confirming my suspicions. Here is a closeup of the excess metal between the leaves. Looks like something left over from a casting process (I'm sure it has a name).

And the spotlessly clean pins Bob is referring to. And does this buckram look correct?
