Floor safe found in newly purchased home.

My dad recently purchased a new home. We ripped up the awful flooring and discovered this safe cemented into the floor inside of the basement closet. There was water damage from Hurricane Sandy so it is a bit rusty. No key or combo... We asked the previous owner and they didn't have the slightest clue it was there.

The house was built in the 50s but the safe looks pretty modern to me.

I am expecting nothing but must admit, my Imagination is running wild.

The tools you see were used them to remove the floors and molding around the base of the walls but I am tempted to give it a go at breaking this baby open. Should I break it open or call a locksmith?

Naturally, I will keep you curious imgurians updated when we decide what to do. Fingers crossed!
