If you’re into the modelling scene and are interested in such things, Poseidon Shop have updated their page showing the latest work on their Seburo M-5 prop (art illustrated by Kenzi Teraoka & Takayuki Goto from the series Stand Alone Complex).
The production kits are currently being delivered to their shop at the moment and will be shipped out once they have the instruction set and certificate for each kit ready. The kit should hit the shops at the end of February. If you’re in Japan you can order the kit on their pages here.
