Win. 94 Commemorative hammer won't stay cocked?|Winchester Rifles|Forum|Winchester Collector

I just bought a Win. 94 Commemorative from a auction site.
The rifle appears to be like new and fired very little. However!
When you cock the hammer back,by working the action, it will not stay cocked. If you cock it by hand it will.
Also the little safety pin under the receiver, that the lever must push up to fire.
Appears to be stuck in the up position. I’m going to have my local gun smith look at it.
But any ideas on what might be wrong?
Thanks
