Well, then, another undocumented change.
It would appear then, if Model 611 received the upgrade, the 610 did as well since we have two examples here with the "moving" glowing arrow. Philco just chose to not mention it in their production change notices.
There will be a piece of amber plastic behind the dial scale with three holes in it, coupled to the band switch shaft by a piece of metal that acts as a lever, moving the plastic (known as a shadow mask) as the band switch is turned. This causes a different hole to line up behind the dial scale, corresponding to which band the band switch is set to. On AM, it will reveal the lowest arrow, etc.
mandh, if you're still lurking, sorry for the misinformation.
