This puzzle was amazing . It was very challenging with many very small pieces and intricate detail of everything. This puzzle has received the most positive comments being on display in my office. Be sure to pay attention to the assembly instructions and tips, make sure that you sand and wax every part that to insure ease of movement, and allow lots of time to assemble. This is the highest level of difficulty of the 40+ puzzles I have assembled

I have completed 10 models of varying complexity from Wood Trick, but this one is the grand master. I have thoroughly marveled at the intricacy and accuracy of this model. It is without question the most challenging model I have done yet. I had gone wrong a couple of times and had to do "a rebuild" because I had not waxed the gears properly to prevent jamming. The attention to detail is extraordinary like the oil barrels or the staircases. I love the mechanical mechanisms. How can Wood Trick better this - I don't know. Some parts were a bit difficult to extract from the sheets which was a bit scary as I had to be careful not to break any. Past experience from building other models was a definite advantage.At 80 years of age this model is a great pastime.

Another great build from Wood Trick. This is probably the most challenging so far. That's what I like most about it.

I'm still not finished with this model and would not recommend it for beginners. The gear assembly to raise the structure is quite complex and challenging. This is my third build and am thoroughly enjoying it!

Delivered on time and in excellent condition… highly recommend.

My husband loves all types of puzzles and many times they are simply too easy for him (He's retired and apparently has nothing better to do) He quite enjoy putting this together. The pieces are good quality and there are spares for some parts. This is not for beginners! This kept him busy for the week, he only works on them a few hours a day. Great puzzle.

I've done many of these kits, this is by far the hardest. Definitely not for beginners. The instructions are very clear and if your patient you can do it. Just one problem, there is not enough wax and sandpaper that came with it. But not that big of a deal. Just went to Walmart for some more.

Above average skill needed to build but turns out as a nice-looking model that you can raise and lower.
