This history seems to say that it was redone in 1905 because of changes in printing technology, and 1⁄3 was redone in 1973. I think there was continuous small turnover, too. [This] says that 113 engravings were added in 1887, which is adds up. But it might just give that number because it was a larger than normal change.
I think it still uses the original art. Haven’t checked, though.
