Are you aware of the G-tec company that makes a mixer for the Smith AT-61 but has a separate screw-on elbow that has Victor threads on the tip end. This allows for the Smith AW1A torch handle to use Victor TEN propane tips. And with a Paige adapter it is also possible to use Meco and Paige tips as well. The separate elbow uses Victor threads on both ends. They make 2 elbow lengths. Incidentally, they also make a mixer for Victor and compatibles. And in addition, they make clones of Victor TEN tips out of brass (instead of copper).

Here is a picture of mine with their brass TEN tip. The other one with the short elbow fits Victor torch handles. Remember that both elbows can be unscrewed from the mixer.
