Do any of you have evidence or thoughts on what color the 59, 60, & 61 (primarily the later) gunboats had the 40mm Bofors, and the BMG's painted?

I'm sure that at least some of the BMGs (stand and shield) were painted to the gunboat's color bunt am unsure that a field paint job was applied to the barrel and receiver.

As for the 40mm Bofors, if the whole gun was basically an Army gun modified to sit on the riser on the deck, was the whole gun repainted?

Hope someone has a good answer. Thanks, Lew

While I am not a gun expert, I do not think you would paint the .50 BMGs.

Charlie;
I am sure Lew meant the .50 shields and the pedistal mounts and base plates.
Take care,

Concur on the shields and pedestals, which he says, but he mentioned field pain to the barrel and receiver is what I was responding to.

Understood Charlie.

Lew;
the barrels of the machine guns were/are gunmetal (Testors model master color).
In real life they would not be painted. The paint would be burned off within a few rounds.
Take care,
TED

The .50's were almost entirely Parkerized on the outside surfaces, a porous coating that held oil. Here's a good excerpt about the color of Parkerizing from http://www.brownells.com/aspx/NS/General/DisplayPDF.aspx?f=Inst-482+Parkerizing.pdf:

PARKERIZING COLORS
An Historical Perspective by Scott A. Duff


If you want to start an argument among collectors of U.S. Military Small Arms ask: What color Parkerizing is original? This seemingly simple question will provoke endless discussion, and provide a wider variety of answers than one could assume possible. Research conducted in the preparation of several M1 rifle related books has provided the opportunity to examine thousands of Garands, including hundreds of rifles in original configuration. Observations indicate the color of the Parkerized finish varied with the conditions under which the Parkerizing was applied, the era of the rifles manufacture and the condition and length of time they were stored. Specific factors affecting the color resulting from the Parkerizing process include the type of phosphate used, the temperature and duration of the process, the saturating oil bath, and the preservative coatings reaction on the compounds contained in the Parkerizing. In addition, the method and chemicals used in heat treating and the specified hardness of the individual component also affected the finish color. For instance, a softer metal has a darker finish than a harder one. Descriptions of variations in color and shade are subjective, and the same finish may be described differently by two different people. With that in mind, original finishes have been observed which are: charcoal black, gloss black, black with a noticeable green tint, dark olive green, a light, almost translucent gray, and translucent gray with a green cast. The earliest original rifles examined are in the collection at Springfield Armory National Historic Site. These rifles, serial numbers 81, 87, 79115, 100,000, 1 million, 2 million and 3 million, are in as-new condition. They were deemed of historical significance, and generally transferred directly from the factory to the museum shortly after manufacture. They all are of charcoal black color. Early production Winchester M1s are of the same color. None of these rifles have been coated with Cosmoline or saturated with oil. It is interesting to note that M14 rifles were not subject to Cosmoline coating and are the same color as these early Garands. Other M1 rifles manufactured during this era which have seen service, have been observed to be of gloss black or dark green finish. It is believed that the gloss black is primarily a result of repeated cleaning with solvent and oil-soaked rags which gave an almost polished effect to the finish. The frequently encountered, dark green Parkerized finish is believed to be primarily a result of the compounds present in the Parkerized finish chemically reacting to the Cosmoline used for corrosion prevention during long term storage. Observations of original Garands manufactured by Springfield and Winchester indicate a change in the finish color from black to a translucent gray during the late summer of 1944. The Parkerizing process used to finish M1s of post World War II manufacture appears to have returned to the charcoal black finish. If the rifle has been stored in Cosmoline, a green tint may be noted, So, what color Parkerizing is original? Most as new Garands are charcoal black. Original finishes of gloss black, black with a noticeable green tint, dark olive green, a light, almost translucent gray, and translucent gray with a green cast have been observed. The variables mentioned above and more than fifty years of use and storage make it impossible to give a specific answer. However, one thing is certain; the argument among collectors and aficionados will continue.
