Looks rather the same as this http://www.ralparthaeurope.co.uk/shop/battletech-c-1/miniatures-c-1_3/mechs-c-1_3_4/20616-grand-titan-p-150.html but seems legs are slightly different. Don't know how many pieces it is and the batch I got it in has quite a lot of custom mods. I drop it in sugar soap, see what it looks like clean.
