Does anyone know if the steel butt pad is the same for the supergrade vs standard grade winchester? Anyone know a source?
Thanks

They used the same steel butt plate for both. The featherweight used an identical aluminum one. Originals come up on Ebay all the time. Check there. Replicas are available. I've seen a couple of them but I didn't really pay attention to how closely they matched the original.

And they run the whole spectrum on sizes, both width and length.
