There is one important thing missing on the 1826-1855 iteration of the DC Capitol Building. That would be a 24-31 (or something like that) star US Flag.
This is highly possible that I simply failed to run into one while googling, but see for yourself. May be you could find a photograph with one. All I got was either none, or cut off flag posts. Do not offer drawings for obvious reasons.
KD: If you find a photo with the US flag, please post it here. And if there are no photographs with the flag, what could that mean?
