RE: -75 dB

The two engines were built by the London Science Museum in '89-'91 for Babbages 200th birthday and in '00 they also built the printer.

The Smithsonian may have one of the engines based on the Babbage design and built by the swedish lawyer and inventor Per Georg Scheutz and his son Edvard. They sold one to the US gov in 1860. I can't find anything that may indicate that the Smithsonian ever built one for themselves.
