From the update:
I have just posted up images of the figures for the Ramshackle Games "Iron Borthers" Kickstarter campaign.
The one standing up straight measures 29 mm to the top of the crest on his helmet, so they are true 28mm figures. The models are shown with the "Iron Brother" heads.
Please note that the image contains a scale shot with a Games Workshop Cadian Imperial Guard. This image is for scale purpose only and is used without authorisation from Games Workshop Ltd.
The models come as three parts: body, head and gun with hands attached.
The penultimate row shows the Weapons Specialists, left to right Plasma Blaster, Flame Thrower and Thermal Gun. It also shows an unfinished "work in production" image of the Squad Leader. He will have a choice of two guns.
