I think there may be one for sale on 24hrcampfire- it's a non-checkered (walnut) stock- evidently sold by the Winchester factory at some juncture, has the schnabel forend- actually looks pretty darn nice w/o the checkering. Not sure if it's LA or SA though and not certain if it's one or two piece inlets on it.
There may be more than that one for sale on that site, I just accidentally bumped into that one.
I decided to keep my wood Featherweight stock when I couldn't find anything significantly lighter AND it just looks good
I have a red pad pre-64 stock for a 375h&h my father in law asked me to list. I don’t think it’s a featherweight, it looks like it wasn't treated like a safe queen, and there is some sort of bedding compound in the fore end.
I don’t want to waste your time if it’s not what you’re looking for but if you want I can send photos.
