Try ABC and XYZ of Bee Culture Published by the AI Root Co ISBN 0 936028 01 7 I have the 40th edition, on page 342 is a construction diagram for a 6 frame observation hive, most that I have seen contain only 4 frames, the diagram looks good and is a USDA Extension drawing - so maybe you could get the plans from them too.
