Lorenz cipher machines were built in small numbers; today only a handful survive in museums.

In Germany, examples may be seen at the [[Heinz Nixdorf MuseumsForum]], a computer museum in [[Paderborn]], and the [[Deutsches Museum]], a science and technology museum in Munich.<ref>{{cite web | url=http://www.deutsches-museum.de/en/exhibitions/communication/computers/cryptology/ | title=Cryptology | publisher=[[Deutsches Museum]] | access-date=30 October 2014}}</ref> Two further Lorenz machines are displayed at both [[Bletchley Park]] and [[The National Museum of Computing]] in the United Kingdom.  Another example is on display at the [[National Cryptologic Museum]] in Maryland, the United States.

John Whetter and John Pether, volunteers with The National Museum of Computing, bought a Lorenz teleprinter on [[eBay]] for £9.50 that had been retrieved from a garden shed in [[Southend-on-Sea]].<ref>{{Cite news |first=Paddy |last=O'Connell |date=29 May 2016 |title=Secret German WW2 Code Machine Found on eBay |url=https://www.bbc.com/news/uk-36401663 |publisher=[[BBC News]] |work=[[Broadcasting House (radio programme)|Broadcasting House]] |access-date=November 6, 2016}}</ref><ref>{{Cite news |first1=Damien |last1=Gayle |first2=James |last2=Meikle |date=29 May 2016 |title=Device Used in Nazi Coding Machine Found for Sale on eBay  |url=https://www.theguardian.com/technology/2016/may/29/nazi-coding-machine-lorenz-teleprinter-ebay |work=[[The Guardian]] |location=London |access-date=November 6, 2016}}</ref> It was found to be the World War II military version, was refurbished and in May 2016 installed next to the SZ42 machine in the museum's "Tunny" gallery.
