Mike,
That old warhose was propably used in the Greek Civil war which followed WW2 as well.

I recently got back my small ring M98 which was my first rust blued rifle and I really like it compared to hot bluing. Its hard to describe but its almost like it looks more like part of the surface of the metal rather than a coating on top of the metal. Also in your case, I think the colour of the rust blue will compliment the case coloured parts better and will tie it all together nicely.

Finally, I like the fact that you kept and highlighted the original reciever markings. Can I ask how the gold colour was applied?
