WTB Skinner Express peep for Marlin 336 (Glenfield 30A)

[Huntnfish89]

Please move if this is in the wrong section.

This is a long shot, but I am looking for a Skinner peep sight to put on a Glenfield 30A 30-30. I would prefer the Skinner express, but honestly would be open to one of the Williams FP or Lyman sights that attach to the side of the receiver as well.

Thanks!
