I went to the technology museum in vienna this summer, and took some photos of various fiddly machinery bits! 
They have been taken with a blackberry curve, so its not the best quality ever, but i did take them through photoshop to balance them out a bit. They would make terrible texture sources, but great reference! I figured they'd come in handy with all the interest in making machinery and such on here lately, and ofcourse for the neverending brycean quest for more 'stuff' to use for detailing.
