More than a decade of experience and handling/working on MANY guns.

so youre certain that the gun is hot blued ?

Brian is a master at his craft I would trust his opinion.
There typically shouldn't be bluing on the lugs or extractor.

not saying i dont, but he said earlier its possibly hot blued, im just trying to confirm it.

Think Brian was being considerate by saying "possibly". Meaning...it was hot blued.

You should also have picked up on the second statement about the hot blue being "not good" and ask if he meant something other than its collector's value.

Well, you are asking me to concretely say, over the internet and without having the gun in hand, if 100% certain the barrels are hot blued. I cannot and will not do that. I will say that based on what I see, from the photos you show, the barrels were more than likely Hot blued. The lugs are not the only clue. But it is a good one.

If you want a definitive answer, then Get the gun to someone who knows what Hot bluing is Vs. Rust bluing and the appearance of both, let them see it in person and have them tell you.

Im more so asking what to look for to confirm that the gun is hot blued. I have a local gun smith that i go to here, ill ask him about it tomorrow.

thank you for your feedback

im aware that a hot blue will eat the soder that holds the barrels together.
