A display of the different versions of vertical ASA's that have been created over the years. Take a note that some say mini, there were used on Mini-cocker Bodies located directly below the front block. Another fact that many people don't know is that pre2k bodies were squared off on bottom at the point where the vert ASA's mount. So when you see Pre2k now you know why. As a side note; the pre 2k vert ASA's will work fit on newer bodies, but with a gap on each side. But the 2k+ vertical ASA's will not fit on Pre2k bodies.
Enjoy,
