5 inch gauge raised level driving trolley with water tank

A seriously grubby 5 inch gauge driving trolley, recently unearthed from the stable attic where it's languished since we moved up here in 2004. I remember hoarding it away as, despite its revolting appearance, it is substantially made with nice cast-iron frames bogies. Worth restoring, as I remember it once had a water tank for the front - if it hasn't been converted into something in the meantime I'll see if I can dig it out.
