If you blow the picture up , the driver's visors on the 3 and 6 do look different , not much , but they are different . The hatch on the side of the engine should be two piece , split in the middle , either one piece folds up , one down , or a double fold to the top . Pictures I looked at aren't that clear . The model renders do'nt show a two part hatch , BUT , there are BA-3 & 6 pictures on the net with a one piece side hatch . Was it a retro fit , different part manufacturer , or was it a GAZ truck part ? If needs be we can always scribe a line ( if Rubicon is wrong ) or ignore it all together . I'm more interested in an accurate looking turret / crew compartment than a side engine hatch . Any thoughts , guys ?
