Timecast is hoping to get the Landmark range of 15mm terrain back in production.
From their website:
We are currently talking to the company that manufactured the original batch of Landmark buildings and are hopeful that we will have most of them back in production later this year. This will depend on financing the production but at the moment we are quite hopeful.
In the meantime we have limited stocks of the last two remaining models so… if you want some of these excellent ready painted model buildings get ’em while you can.
