I recently placed my model kit of the Mark I on Ebay.de. It's the Firing Line Mark I in the scale 1/15. I bought it a month ago but seems to difficult for me to built. For years I'm a plastic 1/35 kit builder and tried (with succes) several figures in the scale 1/15 or 120mm.Mostly the incredible German soldiers of Jon Smith Modellbau. But the metal kit of the Mark I is other stuff. So if anyone is interested search on Ebay.de under panzer ww1 or tank WWI and you will find it.
