Colt Buttstock Help please

[protouraero]

Please help me ID the buttock in the below pictures. Tried to do it VIA Google but didn't find the exact one.
All help is appreciated.

Butt Plate, Colt only built a few rifles that used butt plates in its history.
I'm sure Leadeye will see your post and chime in with what rifle it's for.

I'm going to guess a Colt Lighting.
