Object somehow reversed in position I'm not sure how this happened, but my object appears to have been reversed completely in it's direction.  I tried using mirror (both the modifier and transform tool) and all it does is revert back to its current position.  Any idea why this has happened?  It's like the object has somehow been mirrored but I can't make it face the right direction.
This is how it's currently facing:

As you can see from this picture, it's reversed somehow from the reference photo:
You can mirror your object along its pivot point by pressing , then CTRL+M and in this case pressing X to mirror along X axis. 

It appears that the problem was due to a rigidbody on the piece interfering with transform operations.

Your rotation and scale are unapplied, be aware that modelling on a non uniformly scaled object will cause problems.
