There don't appear to be any examples in the typewriter database, so be sure to create an account and upload the data and photos you've got. https://typewriterdatabase.com/register-today.php (It's not every day someone gets to upload a new make/model!)
Similar machines and details: - Gundka https://typewriterdatabase.com/no_info.414.typewriter-serial-number-database - Frolio https://typewriterdatabase.com/no_info.415.typewriter-serial-number-database
By drilling down into the database and looking at pictures and descriptions of other models as well as looking at the galleries for specific examples, you may be able to troubleshoot what is missing or "off" on your machine (which is obviously missing the spools, though you may be able to fashion something similar to get yours working.)
Other examples via online search may be helpful as well: - https://www.glennsantiques.co.uk/shop/p/02/060/11 - https://www.worthpoint.com/worthopedia/vintage-toy-typewriter-emg-dover-1000802769 - https://www.ebay.com/sch/i.html?_nkw=EMG+Dover+Junior+typewriter&_sacat=0&_from=R40&_trksid=m570.l1313
Documenting your own example will make it much easier for collectors in the future.
