I could find that Adg and Peterson use induction.
If some manufactures use flame they would have very highend metalurgy labs that the mere candle annealler doesn't have access to.
You need to read Alex Finlays book as it's an outstanding insight as to why flame annealing is just total guess work with variable results.
End of story.
