S&W model 67

[calrim]

My new (manufactured in 2011) s&w model 67 is a 67-5. I was under the impression that the latest (since 2004 or so) model 67's, were 67-6. Called S&W and they say that there is no 67-6 and that they only produce the 67-5. But I see model 67-6's for sale and read discussions about them. What am I missing? Can anyone please educate me on the dashes? Thanks!

Bought a 67 less than a year ago new and it is a 67-5. Not sure what the 67-6 is and am curious now too.
