My third and most difficult model from them. The instructions are the best yet but some of the smaller parts are quite delicate and must be fitted very carefully. Definitely not for short attention spans or tempers. But when finished it is another marvel of ingenuity with so much action built into the model. Excellent way to spend a couple of evenings assembling it and admire the precision design and cutting of the intricate parts. No glue nor messy paint but an exacto knife comes in handy for cutting the toothpicks to the proper length to use as hinge pins or axles. Overall, an enjoyable exercise- especially for rail fans.
This is a Christmas gift for a 12 y/o. who likes to take things apart and put them back together
Our grand son Loves the challenge of these puzzles and his parents LOVE the idea
he isn't on electronics all the time.
Great Gifts!!!

Ran across these 3D wooden puzzles a few weeks ago and have put a few together. I have found them to be both challenging and a lot of fun to put together.I highly recommend them.
