I was lucky that this one was for sale in my own town. So I took my bike and found the adress (thank you, iPhone, where would I be without you?).
The lady gave me the time to test out the machine, and my heart was immediately in joy when I saw there was still an old paper in it.... It was typed by a lady who called herself Grandma Nelly, and I couldn't stop smiling because it were texts of silly Dutch songs.
Now my fingers are black from changing the inklint, but of course I couldn't wait to type something myself.
