Not a stupid remark straffo. I've thought about that.
If the cockpit was closed, the main canopy bars(upside down "U" shaped doohickey) would thicken a bit more, and come something close to the size of the bars in Nate's pic.
But the real problem is the frontal struts(two vertical bars left and right of the gunsight). Even if we take into account that the Fw190A-8 thicker armoured glass(IIRC), the frontal struts are way too thick.
Also, the area of the windshield (which is transparent, thus offering visibility) surrounded by outer cockpit bars(the big upside down "U" shaped doohickey) are too small.
Thus, the overall size of the main canopy bar(the upside down "U") is pretty good, but the visible areas surrounded by it are two small, and the frontal struts are also too thick.
