Does anyone know what bluing was used on early 1906 magazine tubes?

Supposedly they tried a cheaper alternative to rust blue and used an acid etch followed by a low temp niter blue on the barrels .

  This is about the 1890, but covers the 1906 as well.

  I have Ned Scwhing's slide action book on 1890/1906 which was quoted in that thread a lot.

  It was in that book that he speaks of the acid etch and niter blue "dump" bluing he called it.

  Normally niter blue was a 600F temp blue used on springs, extractors,loading gates etc. But his book stated 275F niter blue over acid ?

  Anyway the 1906 barrel blue was not rust blued and generally never survives in good condition.But often the mag tube finish does .

  Not sure if they machine blued them or maybe the metal difference made them take finish better and were dipped same as barrels.

  Mind you I'm talking early production pre WW1
