We took photos of a number of Browning guns on P-51's, and did our best to make a facsimile. Most of the ones we see today are lacking the bronze / gold color referred to here. But it was a consideration. I chose to leave the guns in their natural silver finish.
"The Brat", a nice example in Addison, TX.
And mine...

I've always wondered if the NACA scientists mentioned to North American that their whiz-bang laminar airfoil would be rendered neay useless by the gun barrels.
Looks pretty good TX. I noticed in one of your pictures that the barrel bushing is set back from the barrel jacket.(highlighted below) The barrel jacket had screws through it that retained the bushing flush with it's end.(shown below)
I'm not picking on you. I'm just trying to help you get this to as close to the real thing as possible.

Yes, my goal was to get these to look as authentic as possible (within reason). I had an option on the inner barrel, to recess it back into the housing more like the actual P-51.
But my barrels actually whistle (all 3 of them), and the inner barrel has the loudest whistle...not sure why as it is the shortest of the three.
So I went with this configuration in hopes of recreating that iconic P-51 whistle when inflight with high angles of attack.
I fully understand that you are being helpful, and your input is greatly appreciated!

It was discovered that the traditionally whistle one hears when a Mustang passes by caused by the six .50 caliber barrels. Looks great too by the way!

To make it look truly original, place pieces of tape over the barrels instead! LOL

So Nice My Friend.

It's my understanding that they taped the barrels so the ground crew would know if the guns had been fired, after returning to base.

Here is some interesting info, related to the guns on the P-51.

Don't get me started on that whole P-51 gun whistle myth. I'm not sure where it started but pretty soon people are going to start taking it for historical fact.

Gee, Deuelly, I thought that everyone knew.
It happened at a hunting camp in the Louisiana swamp, about 2330 hours, around a campfire. Boudreau had just finished a longneck, and was trying to get one more drop of beer, when he unexpectedly burped over the bottle opening, making a brief whistle. Thibodeau heard it, equated the opening in the longneck with a .50 caliber, and immediately knew why a P-51 has a whistling sound.

I took an air hose and held it up to my gun barrels (.410) with a fast stream of air blowing across at a good angle of attack, just like if you were pulling up hard from a low / fast pass.
All three whistled, very loudly, in different pitches. We are all anxious to see (hear) if they will whistle inflight.

I am very interested in what you think is the cause of said whistle or the unique sound in which everyone is making reference to?

Do a search on YouTube, or FaceBook. The answer is there.
