Wow! Those are wonderful collections! Dear colleagues: my first portable was the Diana. It was covered in green rexine. And I got in love with it. I bought it one day at the flea market, somewhat like in 1982 or so... for 3000 Ptas (equivalent to 18€). Then, one 78 costed me 50 Ptas (0.60 €) usually.
In a few days the spring

broke at the middle! With no internet, no books, no collector colleagues... I had to take myself to the task! So I heated the broken ends in the kitchen gas fire, made two holes and added a short bolt& nut, and it managed to work this way for some more months. Yet then I had to repeat the operation! Later I managed to get a new spring, years later! Oh, God! How I remember that smell of gramophones and how much I liked it.
One day I decided to revamp it, and bought a nice red rexine and recovered it, fairly well! Now I represent having done that. I'm planning to revert it to is original aspect. This was my only machine for 14 years!
Thanks for your answers, colleagues. This is a very nice forum!
