I can recommended the Jarvis LKE-1 "Lung Gun":
http://www.technex.pl/supplier/Jarvis/engl/lung_gun.htmIt probably won't help you much with Aces High, but it's a fascinating conversation piece.
I'll quote from the product description:
"JARVIS MODEL LKE-1 PNEUMATICALLY CONTROLLED LUNG GUN FOR HIGH-SPEED REMOVAL OF POULTRY LUNGS AND KIDNEYS
--Ideally suited for removal of chicken, turkey, duck, and goose lungs and kidneys
--Operator fatigue and error is reduced by the unique air trigger system
--Instantaneous vacuum-the usual delay associated with conventional guns is eliminated
--Easy to clean for optimum hygiene- simply suck disinfectant through with the vacuum and spray externally"
It's just one of the many reasons why you should never offend someone who lives in farming country.
