You guys are fantastic. So here's one I've been curious about but didn't think I'd be able to find any details on. I have the three F7's pictured below, neither of them are the same. When I bought the "Digital Commander set" way back when, it came with the 4 circular window F7. I already had the 2 circular window version and the no window version.
We all know that they are all F7's but is there any additional details you could provide regarding each of these, such as, their different year manufactured or why the windows were added or removed, or due to what the different railroad companies specified, etc.

The info you provide will support my museum on the layout. And yes, my museum is still under construction, which I might add these locos to it.
