If anyone needs a gun for prop purposes my son makes life size ones out of Lego!!
His bedroom's like a bloody armoury.
His knowledge of guns is encyclopedic, came in handy when we had armed police outside our last house (looking for whoever was setting off massive explosions on Towneley fields. Never made the papers, naturally) he calmly told us the make, model, year of manufacture, size and type of ammo etc etc.
Perhaps I should be worried!!!
