Bob. Ron and Fred will tell you that the Bucks "school" is not an easy choice for a first build. Like the Lehigh, it's either right or it isn't. I have seen examples done by well known gun builders that either lacked correct details or, most often, were just too bulky. Fortunately, this forum has guys like Ron, Fred, Taylor S. and Tom Currie who have made excellent recreations of this, unique style. I can help with photos of details and send you my KRA article on the "school" that might help a little, if you're interested.
I remember following Eric Von A's first Lehigh some years ago. He put a lot of time into research and questions and was rewarded by a pretty nice example. You need to do the same. Research the components and architecture and, as moleeyes said, avoid the "kits" out there.
