Black Cat Models of France continues to release new 3D printed subjects.   Among the latest releases is a set of 1.1 inch quad gun mounts, 1.1"/75cal quad mount gun mk2.  This weapon was used widely on USN ship in the late 30's and during the early part of America's involvement in the Second World War.  However, the weapon was found to be unreliable, prone to jamming and ineffective as an AA weapon, according to   While it was quickly superseded by the far superior 40mm bofors gun, it was still found on smaller vessels until the end of the conflict.  For more on this weapon, check out

The packaging is Black Cat's non familiar plastic clamshell container.   There are two 3D printed runners in the package.  One holds the top half of the mount, with the barrels, while the other holds the base for the weapon.  Both runners are secured to the bottom of the packaging with thick double sided tape,  which prevents the runner from moving during shipping.  As with earlier reviews of Black Cat products, to avoid breakage while taking photographs, I left the parts affixed to the tape.

Some of the details that stand out are the fineness of the gun barrels and the plumping and piping on the base.  The only thing not present are the hoses that connect the water recirculation pump to the barrel cooling jackets.

Below are photos comparing the Black Cat weapons vs. manufacturers versions, where you can see the higher level of detail on the 3D printed parts.

There are no instructions in the box, but the packing directs you to the Black Cat Models website.   There, on a data page for the particular item, you will find instructions on how to remove the printed supports that are part of the 3D printing process.
These 3D printed set of 1.1 guns are really well done.  As with previously reviewed Black Cat products, the print quality is very good, the details are excellent.  I'm especially impressed with gun barrels and some of the details - like the seats and plumbing - on the base.   As seen in the photos, these weapons will certainly be an upgrade to most kit supplied parts. 

This is Black Cat Models set AC350007, 1.1"/75cal quad mount gun mk2.   This set of four weapons retails for about $9.50 USD, and are available directly from Black Cat Models, as well as some of our other sponsors.   Highly recommended!
