Hello - I found this patch in my line of work, and am intresting if someone can tell me what this symbol means or what it stands for.

The only thing close to what I got is something from the Freemasons, 'The Triangle' , wich is also with keys upside down, but there are only 2.
In the picture I have there are 3 and the right one seems to show a crucifix.

If anyone has any idea, please help!

Thanks!

That image is similar to the keys to the Kingdom of Heaven that Jesus gave St. Peter. They have been depicted in various ways. The left two tops of the keys don't look familiar as to the bird that announced the beginning of the Passion or the Papal Tiara. There is a picture on this website.

It could be a greek letter in the top of the keys, or it is another religion making up their own aspect of belief based on the original symbol.
