Sorry the picture isnt the best it was taken with my cellphone on my front porch while it stopped raining and cleared up a little plus the plow has a couple layers of paint on it
If I had to guess I would say its made of resin from a mold, the coupler mount is actually part of the plow, I just cut a straight kadee coupler in half and left about 1/2 of the bar out the back and glued it into the mount, perfect fit and its at the right level to actually be functional but because its glued in and cant swing left or right any I cant make any use of it with my R3 curves still looks better with a coupler than without
Here is a picture of it on another one of my Big Haulers prior to the coat of paint it has on it the picture above and also prior to gluing in the coupler
