Update:
I have been able to ascertain that the annex was reconstructed starting immediately after the fire that destroyed the annex. As a consequence, I have identified this as the state of the annex after reconstruction. Accordingly, I have moved the date of this video from 1920-1927 to instead be 1927-1938.
So, after posting this video I realized that, chronologically, I should have posted another video first. So that one will come next week instead. I guess.
Changes to the temple in this video include the removal of the parapets at the top of the stone portion of the tower, these were replaced with the fence like structure we know now. Also in this is the painted parapets on the rest of the temple, which were painted to look like sandstone. The annex itself was redesigned both inside and out, though the exterior structure was kept from the burned out original.
