Crystal Palace Company Constabulary Police button

Unusual large 25mm white metal button  depicting the Crystal Palace building as it appeared at the Great Exhibition of 1851, the label on this button stated it was from the The Crystal Palace Company Constabulary, whilst i cannot find any other documentary evidence this makes sense

The Crystal Palace Company controlled everything that happened within the building and the surrounding parkland. Like Disney today, visitors were charged an entry fee which allowed them to use or view all of the Palace’s facilities, making this the world’s first major theme park.
