This is an original & authentic M57 "Clacker" Detonator for the Apers Claymore Mine.  This is not a training model, this is the real deal.  The photos DO NOT show the clacker we have in stock, as we are still waiting on photos, however, the unit you will receive will be in much BETTER condition than the one shown here.  Usually on these old clackers, the rubber seals are cracked & ripped apart from tempurature/humidity changes in decades of storage, but the rubber seals on this unit are all in great shape, so you can clack without guilt.  
 
Blackhawk Down, Hurt Locker, Predator, Tears of the Sun, and many more legendary movies have prominently featured this detonator!  These are only getting MORE collectible, throw this in your man cave so you can stare at it for 10 years and then sell it for multiples of what you paid!
