It probably took me about a week to make. It took a couple of days to cast the blocks and the rest to assemble it. Because of the way I built it, I had to put a few layers together, then paint, then assemble more, then paint and so on. The Hirst web site, www.hirstarts.com, shows all of the molds they have available and has a lot of good tips and tricks to help design and build just about anything you want. The molds were originally made for 28mm scale, but the Fieldstone line works great for 15mm. The mold I used for this tower is mold #70, Fieldstone Wall. Let me know if you need more info.
