After so much elbow ~~oil~~ grease (thank you @Mouselemming@sh.itjust.works ), this is the result I'm proud of: A working Graziella, ready to take me around Salento (area in Pulia, south of Italy)(maybe that's too much... maybe I'll move just in the town ๐
)
There is still quite some rust, but the pedals flow and the brakes work well (enough).
Do you know this old folding-bike style? The original one was called Graziella, in the '60s, and then all the Italian manufacturers produced their version. But I think it's not known outside of Italy. Cheap, sturdy, practical... The old ones sell for a good price, if in good state (not this one ๐ )
Also a picture while I was restoring it:
