IIRC, the 6 1/2" barrel length was dropped from the catalog around '68. I have two nice boxed 27-2s, and one or maybe both shipped in '72. Took me a long time to acquire them, but not as long as the boxed -1 I purchased at auction, and the only one I've ever had an opportunity to buy. I also have a couple no dashes, and a few pre models, which were far easier to acquire--they made a lot of them.
