C Otto Berlin, upright piano

[mac101]

Hi,
Just wondering if anyone can provide any information on a piano that i was given years ago, it now sits in my garage since the children are no longer interested in it.
I'm guessing its from 1904 going by the tuning records scribbled inside?
Thanks in advance

The tuning dates are often a good clue, I would have put the Lexow number around 1903, but that's close enough. I know very little about C. Otto. The main number seems to be 14509, but it doesn't line up with Carl Otto's numbers.
