You are the first person I've seen who has documented the building of the Evergreen other than myself:
ModelShipBuilder or
ModelShipWorld
This was my very first wooden sailing vessel of any sort. At the time, I knew absolutely nothing about sailing vessels or how to construct or rig them. I found no historic pictures or pictures of models by other builders. Still, I wanted to add more rigging detail, so I looked at pictures of other schooners and winged it from there. I just tried to make it look like the pictures, so my accuracy left something to be desired.
I completed it in 2013. And I agree with you, it was a fun model to build.
