The quality of this model is outstanding and it was a pleasure to construct. I lost count of the number of nuts and bolts needed to complete construction. Some of the components are very small making the build a challenge with my large 70-year old hands. I did purchase this model to challenge me - it did! The instructions are a series of photographs and a few notes. You must read and digest the instructions carefully before plunging into the build. If a component looks out of alignment, then you have made a mistake. Carefully undo the parts that look incorrectly aligned, read the instructions again and try once more. It is very satisfying to work on a model like this. I will be looking for more. Recommended.
