'42 Lithgow receiver finish, blue or park?

[iringtwice]

The finish on my rifles receiver was removed by the previous owner in an attempt at taking off some corrosion. Apparently instead of using 000 steel wool they used fine sandpaper. My question is during the war if the metal needed to be redone would they have blued it or parkerized it? The barrel is a nice dark shiny blue, at least they left it alone. Here's a pic of what I'm dealing with, this is the worst spot but at least they didn't destroy the stampings!

Original APPEARING '40's vintage that I've seen has been phosphated, rather than blued. Pre-war is most often blued. How many are post war refinishes I've no idea.

I think the changeover from bluing to phosphating came sometime in 1941; and I'm fairly sure that all '42 rifles would have had that greenish phosphate finish.

In 1942 they were parkerized.

Thanks y'all!

I've a June of 1941 (according to the markings on the buttstock + the 1941 receiver and barrel date) that's phosphated. 90% sure, anyways. If not, I'll let y'all know.

It was't newish looking when I got it from a friend who snagged it at a pawn shop whilst on a road trip, but it looks "correct" and the S/N (sans prefix) is 61941. And it was June at the time! Happy birthday, Lithgow, I reckon.

Do you have the responding letter? It would be interesting to see what the reply was.

[Kev G]

No I'm sorry I don't.The plant would have been up and running by Dec 40/Jan41 for Bren production though.

I am very interested in this type of dye to blackened a park finish, can't quite read the name of the dye. Does anyone have any other information.
