Grip identification help

[Magyars]

Attempting to identify these grips, off a smith and wesson N frame.
Inside marked BNC, maybe BNG with the number 4828 on them. Unable to find anything on line.

They look like old Houge Cocobolo grips.

 

[Hookeye]

Badger is my guess, shape is a little different though.

Hogues don't cover backstrap and are attached via stirrup and bottom screw
One pc grip is Hogue.

The grips the OP has are 2 pc, clamshell, cover backstrap....and the fingergroove shape is diff than Hogue.
