Holy cow! What an amazing bike. I've seen many old steel bikes with a humped top tube due to a collision. As long as it's just crinkled paint & there's no cracks in the steel then, it should be OK to ride. (The front wheel is no where near the downtube). I would fix it up & ride it. (Just avoid doing any mile long 45mph downhill runs with it). Have fun. Be good.
