Sorry, don't know this type and very hard to find a similar that could be close to both uppercases and lowercases.
A list of alternatives, some matching lowercases, some uppercases but all requiring customization: Static (the closest I have but /R off and all spurs on lowercases to be removed), Spoon, Rotundus Rounded (not so far but many uppercases off and some lowercases), Tesca, Borba Sans, Module Classic (mainly uppercases), Duepuntozero (mainly lowercases)

Thank you very much. It is an original from the 60's on a housewall in Berlin - hard task, I guess...
