I can't help you with a source , but I can say your lathe is probably a lot more rigid than my old Wards/Logan.
------------------------- I thought they were close competitors.
My lathe spent its early life in a trade school where yearly maintenance was a coat of school color paint, the rest blown on liquor. Oiling it didn't seem a priority. The localized wear prevents snugging up the gibs properly.
I put a used Multifix A tool post on it, which combines the quick change of an Aloris type with the rotation of a lantern post, in 40 steps of 9 degree, so it can position hand ground HSS at angles without losing squareness for a cutoff tool or carbide bit. As long as the point angle of an HSS bit is less than 80 degrees there will be a setting that lets it both turn and face. With carbide the Multifix may have no advantage.
Tools4cheap was near where I worked and carried Chinese clone toolholders which fit fine. I wouldn't have spent the high price of a new Swiss one.
