Actually Bryan, when the breed was first recognised in 1920, it asked for an Otter head, with the same wording as it does now. the only difference being, it said "teeth level" whereas now it asks for a scissor bite, but a level bite acceptable. It no modern fad at all.
The wording may not have changed, but the terrier did, just like every other KC recognised Breed.

I agree to a point, but as far as the head is concerned, its a lot closer to the original written standard than it was to begin with, so thats a plus point. Most are far more "Otter like" than they were before,
