Thanks Ironsides, it did look rather soft which made me worry as to the quality as to the finished piece.
WD Models are doing a 1/76 one which, from the image of the pieces on the website, looks superb - my plan is to make a diorama of a 4.5 inch battery using mainly HaT models relatively hidden (ie in dugouts, under camouflage nets, and positioned towards the back) with WD Models towards the front and in full view
