I know that this topic has been discussed ad nauseum, but I haven't seen mention of this tool before and wanted to share my experience with it.
If you go to ebay.com and search for "goose neck threading tool" you will find the 1/2" shank tool made by mesatool based in the U.S., though I am not sure if the machining of those tools is done here. Does say country of manufacture USA on ebay.

I have not seen this tool on mesatool.com's website though they have a really interesting set of threading tools that would allow the same type of threading with a different insert.
The goose neck tool allows the use of the arthur r warner HSS tnmc or similar inserts to be used upside down and at the proper center height. I have a 40 position tool post and would have to shim the 1/2 shank regular left hand tool too high for use on my machine, an emco v13. I had some issues with trying an internal threading tool on the back side of the barrel and decided to try this.
I have threaded my first barrel with it, and it all went very well with an excellent surface finish. I have recently started threading away from the headstock, and start by making a 60 degree groove at the shoulder to full thread depth. I have also recently had to advance the shoulder of a barrel about .250, and the groove I made allowed the thread to continue seamlessly even while threading away from the shoulder.
For use some-timers this tool may be a great addition and at about $40 was worth it for me. YMMV
