TX's look pretty good. About the only thing to point out is that the barrel bushing is bronze so should be a bronze color. For reference here are the guns in our P-51.

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...

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!

A group of builders in EAA Chapter 292 finished number 1 of 5 1914 DH-2 fighters last year and I decided it needed a faux machine gun. One was built that somewhat resembles an original, at least for 20 feet away. It runs on propane and oxygen and is very realistic. We had to dial back the noise to sound like a .303 instead of the 20 mm sound we were getting. The firing mechanism was a four lobed cam on a gear motor that operated two solenoid valves and a spark plug driver for ignition. It was decided to up grade to an all electronic system and we're still trying to get it to work right. Another example that simpler may be better.

Having a lot of fun with this one...the gun assembly is in it's 4th or 5th generation design.
I have a couple options with the extra barrel sleeves, one set is flat black, the other set is natural aluminum.

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!

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.

Ah, so we can just blame Joe...
