I love mechanical banks.
I have seen the hunter/squirrel, hunter/bear "Creedmoor" and I have even seen the British ones "Tommy" which are soldiers firing at a stump, etc...but I haven't seen a deer. William Tell shooting an apple,
Was it one that the "animal" was in a tree stump...because all I have seen are squirrel and bear.
Rauville, you hit post before me and I forgot to put that link. Glad you did. (Modified this post!)
Is he sure it was a deer?
