Yes it was what I was asking about, can you view all of the four bands through it easily as well? If it did not have that small window for the shadow meter I would wonder if maybe someone fitted that 660 chassis in there rather then the usual 610 or 620 chassis.

Yes Arran, I can see all 4 bands through the dial lens just fine. Thanks for the clarification.
