That situation reminds me of something that happend at old Silverton, near Broken Hill NSW(or so the Pub story goes).


That an old Homestead, was left to this Sydney man in his Great Grandfathers Last Will and Testament, in the mid 1950's.





As circumstances stood, it was worthwhile for him to move the 1200oddKlm(app 1000ml) away from Sydney. As there were certain persons lookig for him, you know Bookmakers, Police %26amp; Loan Sharks.





So he went out there, %26amp; after a little while he tried to carry out repairs and make the place look respectable. As he was clearing a part of the old Sand Stone Wall in the Cellar. He found certain markings on the wall, so he dug a little further and discovered a metal box with Gold Nuggets in it.





It is said, that those stones may have been taken out of one of the Broken Hill, Shafts in the 1930's during the Depression years, and salted away for safe keeping.





Now if you believe that story, you will believe that the supposed Key fits, the lock of the supposed SAFETY BOX.
