Pinard Stethoscope

My mum wanted a photo of a pinard stethoscope for the front of her uni project. We couldn't find an image high-res enough to print out, so I decided to try knocking up my own version in Photoshop that'd be big enough to use. The wood texture isn't perfect as I don't think it'll be used close-up, but it'll do!

Full size attached. On the off-chance you might find it useful, please use! :)
