It turns out that Iconic Replicas (the same company that made the O Scale 2 fishbowls that I currently have) produces in HO Scale the Flxible version of the "New Look" bus, and specifically the two-tone blue used in New York City. https://www.iconic-replicas.co...ew-york-city-87-0238.
The Flxible had sharper angle windows compared to GM's rounded windows and I'm glad to see that it is also available, so I will procure one off the secondary market. End result, I will not be repainting the green HO fishbowl by to the two tone blue and will purchase the ready made one by Iconic Replicas. I might also get their O Scale version of White & Blue fishbowl bus that the MTA changed the colors to in the late 70's now that I see one is made. https://www.iconic-replicas.co...-in-a-series-43-1081. The "New Look" buses will always have a place in my heart.
