searching for a useful image to help out my idea

looking on google images i have tried to search from images of a rusty camera or lens to give me  a good start point for my work however they are quite hard to locate and the only image i that i could find is this one with isn't the greatest image and not really at the right angle however it will give me a good base to work on when adding the worn rusty effect to my own image i think for what I'm wanting to do it is a little to rusty i am just wanting to add a patchy effect while leaving some of the original colour showing trough some people can still recognise it as a camera lens.
