Hello and thanks in advance!

I recently purchased two Treks from a garage sale. One is a 1983 model 520 according to Trek Vintage site and the serial numbers. It has handle bars I've never seen and my internet researching comes up with nothing. If someone could explain how to post a picture of them in this thread I'd appreciate it. For now I can only describe them. The handle bars are drop bars but instead of ending where the usual drop bars end the left side makes a 90 degree turn towards the stem perpendicular to the top bar then ends and the same goes with the right side. What is that all about?

Thanks again and if someone could explain how to upload pictures I will ASAP.
