I am in need of the Nordmende Carmen 57 service manual

[Telios]

Hello, fellow antique radio friends.
I recently inherited the Nordmende Carmen 57 radio. It has been kept in good to excellent condition. But was stored in a clean place for about three years. I need to give it a good check over and cleaning before I actually try
to power it up.
To this end I am looking for a copy (.pdf maybe) of the service manual.
This radio is a Nordmende Carmen Model 57 (built 1957) tube radio.
I hope that someone can help me with this.
I thank you for your time and effort, in advance.
