Just some simple images of an NOS 1500 'N' air cleaner I have stashed away to show the location of factory applied decals and red paint.
As you can see the red arrow on the top is a bit of a poor job but it is there and lines up well with the lower arrow which is pressed into the housing.
Also note that as this is a later 1500 'N' air cleaner and not an early VW-1500 air cleaner, it does not use the large flat washer below the plated wing nut / bolt.
