Guys, please see message below and pictures, I can´t make up my mind what to do. I am tending towards having barrel and receiver rust blued, how do you guys and girls think it would look. I have never handled a gun with French grey. I am a bit stuck so will go with the most popular vote here ! (I trust you all

) see the gunsmith mssg below

"Mike,
The attached photo is of the barrel (which was hot blued) and the receiver (which I ran through 3 cycles of rust bluing). The receiver took to the rust bluing very well;
it may take another 12 to 15 cycles to finish
The photo gives you a fairly good idea of the difference in the gloss between the rust blue & the polished hot blue. If you desire a better match between barrel and receiver,
then I can remove the hot blue, and rust blue the barrel
Another possible option is a different hot bluing process for the receiver, which is gloss finish equivalent to the barrel. To accomplish this different hot bluing, I would have
to send the receiver out. The decision is whether you want the high gloss finish or semi gloss finish on barrel and receiver, or mis-matched finish on the two
The second photo is an example of a Mauser I built with the receiver finished in French Grey; the French Grey can be done in a near gun-metal white all the way up to
a charcoal, and can be done in a matte or a fairly high-gloss finish. It is a very good finish for showing off engraving"
