Victoria:
My guess is this is what is there. If you can get a high-res. picture of this, it would help fill in the details. I see a sword held by a fist (probably mailed) over the centre shield which most likely has the Union Jack inset. Upper left and upper right look like two fusiliers badges, and the upper left appears to be "2". Lower left has a scaling ladder, but the rest of the detail eludes me. Lower right is probably a musket -- or a giant gravy ladle
