Who can identify the rifle this military paratrooper folding stock belongs to?

I picked up this military paratrooper folding rifle stock with a pistol grip and a swivel sling from an estate sale. I thought it might fit an M1 Carbine but I was wrong. Now, I can not figure our which rifle this stock belongs to. Can anyone help me identify it?

Attached are the pics I have taken--hope they are good enough.

Ruger Mini 14. It's the factory folder. They cost enough if you try to buy one...

thanks Jim

Wow. I'm jealous of that thing. My Mini 14 would look good in that.

Maybe a PM would be in order. Sounds like he doesn't have use for it anyway...
