Can anyone tell me......

.....why I've got the gun and my brother (blipper Hamey) hasn't?!  He's got the full gear, chaps, waistcoat, hat and holsters but no gun...!  Taken in our grandmother's garden in....goodness knows when.  I must have been 8 or 9 and T was5 or 6!  Long time ago.  Was I too dominant?  Hope not!
