have the trap got to be a named approved trap heritage,if so would a clone also need to share the same name as the approved one ??? the dukes are fantastic traps ,,some say they ain't as good as the bmi and maybe so,,but in spring strength i would say more power than the bmi....its a clone.. the spring ,frame are a clone ,,only difference is the trip wires dog etc,but under the trap approval bollocks they don't apply... 110 bmi here cost as much as £14.. a 110 duke as little as £3... even when you take the tax added post costs from the us the trap still 50%or less than here... there cries then
