Most detailed, complicated Paper model on the market

[Sakrison]

HMV's Bismarck would be high on the list -- more than 7,000 parts.
Halinski's Yamato is one the biggest, but not necessarily the most complicated.

I would Uhu's Apollo LEM on the list and give Ken West's Apollo CM an honorable mention.

I have the HMV Bismarck but I have never studied its contents carefully. It is amazing. It would take at least 20 years to complete its building if done accurately. Amazing. This model shows how really beautiful and accurate a card model can be.

The most detailed, complex paper model will be UHU02's Yamamoto, if he ever completes it.

Where can it be seen?

He is (was?) going for rivet level detail; the Yamato thread has not been updated in a long time, so whether it is an abandoned project, or the design work is being carried on in private is anyone's guess. The reconstructed plans and parts that have been released so far suggest that he is trying to outdo the SD14 (Untitled Document).
A fully rigged paper model of HMS Victory would fall into the most complicated category.

Surely HMV's Bremen IV must take the biscuit??
6,897 parts and a fairly complex structure. I bought it before I fully understood what it might mean to build it after I'd completed models with less than a 10th of the parts!

In my opinion is that when a model is extremely complicated with thousands of parts, it is very easy to lose interest on it since it would mean dedicating the little free time one has on just one project that might take years to complete. I think that a simpler model, with enough detail and accuracy but much simpler to build, will allow to have more time for other projects.
