Dear Uwe,
Thank you very much for your reply. I am glad to be at the Forum. I recently inherited two typewriters and I would like to know more about them. For one of them, the HERMES Baby, was very easy to find info on the web, including the year it was manufactured since they list it according to the serial number. As for this one, I could not find information.
I do not know much about typewriters. I believe it is electric, because it is written along with the manufacturer, “WELCO”. I tried attaching a picture, but the system does not allow it before I have two postings…
 
Kind regards,
Joaquim

It has a French keyboard, but all of its components indicate that it was made in Japan. The brand name appeared on manual, electric, and electronic typewriters, so it must have been in use for a number of years, and it may be linked to Welco Marketing GMBH in Germany. This is supported by the fact that few of these branded machines seem to appear outside of Europe. My guess without having done any proper research is that it's a private label typewriter made by Citizen or possibly even Nakajima given the almost identical ribbon cover and paper rest used on some Nakajima ALL models.
