Samsung 226bw question

[kensai]

I know there're 3 versions, A,B and C, according what it says on the label. My question is, I've found a 226bw but it doesn't has any letters where it should be. It's empty. Since I don't have the option to try the secret menu which version do you think it is? Any help is appreciated

If you don't see the model# in the secret menu, you have to unscrew the back and read the paper label on the lcd panel.
