Hi John,
Knowing the humidity factors over there, I'm still amazed how well the rust-blued guns came out of there. The only trouble they had was with the bore of the barrels, hence the 7-year barrel replacement cycle.
The brown color on my sideplate is definately not the result of humidity, but the result of some
sort of processing. Other dull-brown finished Dutch lugers were reported, but I never had the opportunity to see one up close.
If 'browning' offers a speedy, cheap, effective way to protect metal parts, it could have been used as a preservative measure during storage prior to blueing.
I guess we'll just have to wait until some more parts (or complete guns) pop up somewhere.
