When that kit was sold they didn't include instruction manuals. It was assumed that anyone buying these kits would have the experience to finish the project. It predates the current take you by the hand and walk you through it builds so common today.
The good old days did have their downside at times.
The construction is a little dated and will force you to learn a few older types of construction or you can adapt it to more modern as you see fit. This is a real nice flyer but is not now or was it ever a quick build.
