My best advice is to get a modern dvd so you can visually see the process and follow along. That and rewind, fast forward,etc to specific parts where your needing more guidance in. Mounting birds is a difficult thing especially for the first few years. If you have the parts, dvd, and get a bird mounted, best thing is to post up some pictures so you can get a critique that can help you progress on the next one. You repeat this process over and over you'll learn a lot more a lot faster and cut down such a high learning curve. I'd be glad to help out with what I can
