Not seen them before.
I can however recommend the Scalescenes Kits, there is a large range of kits available as well downloads of items for scratch building.
Once you have purchased and downloaded the kit you can make it as many times as you want to.
You can also buy from Chrisden Models the pre cut card for many of the kits.
Chrisden Models will be at the Stafford Exhibition over the weekend of 23rd & 24th September.
