Hey Blackpig,
Unfortunatly that's not the case and it costs me an arm to get all those kits (mainly in shipping

).
Well here's what I think :
It looks on this pic that's not a plate but a styrene strip :
I dont think the mobelwagen is glued onto a styrene plate (the gap is probably a shadow because there is no gap on other pics... and this illusion can be see on some parts which dont have any gap).
Plus, you'll notice that the mobelpart is thinner on the side edge than the actual kit part so my guess is that they cut to hape a styrene plate (like I did on the left side). I dont know the exact shape of this one though :
Now a pic with what I think being styrene plates :
I dont know if the part on the left is from a kit of just a styrene plate...
Ive started the plating but ran out of styrene :
Please let me know what do you think !
Thanks
