How can I tell what sanke tap I have???

[Grizz]

I have a sanke coupler or tap here but I have no idea if it's a type D or what? How can I tell the difference between them or if I have a type D sanke? I've looked online for detailed pictures but am having a hard time finding good info. Thanks

Just post up some pics. It's pretty easy to tell the difference

What was originally in the keg? If it's an American beer (Budweiser, Coors, Michelob, Sams, etc) then it's a Type D. If it's a European (Amstel, Heineken, Newcastle, Beck's etc) then it's Type S. If it's a German (Spaten, Warsteiner, etc), then it's Type A. Guinness is Type U.
