Prepare for a long post…
So here is what I realized.
This photo was dated 1948. Is and always was. Let’s note the details:
Singer is missing it’s flagpole, which was removed in 1947. There are no balconies, and the rooftop detailing with the 4 large gargoyles is gone, replaced by metal fencing. The wide windows on the dome roof pop out rather than tapering with the roof, since they were replaced in 1940.
Also note the City Investing Building roof is being covered up. The light part is blue like it was, the dark part is the new gray color it will be.
robermat’s picture from 1951 shows the gargoyles are still intact.
Here it is in House on Telegraph Hill, a 1951 film. Likely from 1950, the cupola is fully detailed, the rooftop details are there, and the balconies restored.
City Investing’s roof is still teal here, but may be beginning to be restored.
1952, from a helicopter. Zoom in carefully, and with a good eye, you will see the four statues on each corner of the roof still. You can also see that the top of the dome roof is blue. If it was renovated, it would be gray like in the supposed 1948 picture. The CIB roof has made more progress in it’s renovation.
Another 1952 shot. You can see down the shaft at each decorative floor that the center of each white stripe is slightly miscolored. Balconies.
And here in 1953, the top of the dome is grey rather than blue, meaning the renovation has happened and the details were lost. The CIB roof is completely gray now.
Conclusion? We’ve been lied to. The picture is really from 1952 or 1953 instead of 1948, and what was thought to be a single renovation that wiped out the details on the Singer Building was multiple.
The true story, which I can attempt to piece together:
We start off with this. Seen circa 1938.
1940: The first renovation occurs. the large windows at the observatory level are replaced, and rather than tapering back they stand vertical.
1947: The flagpole and minor detailing is removed. See the scaffolding.
1952: The remaining detail is removed. Balconies are stripped, the gargoyles and large copper railing on top are replaced with a black metal frame and iron railings.
1952-59: the black metal frame is eventually painted blue to fit with the roof(or the new roof cap was made of some kind of material that gained patina), leaving us with what we have here, circa 1960 from Chase Manhattan under construction:
