Hi! I need an advice from this forum about how can I publish (and where) an original manual (T3079-3 General Purpose Marine Receiver NS702 Type 2207E or G). In 2021 I've created and published the model mimmarconi_marine_receiver_ns702_2207_g (with the precious help of Howard Craven, Edwards † 25.10.21 and Martin Bösch), and now I've digitalized (pdf) the all manual and pictures, but I don't know where can I publish them (the text manual is about 5MB and the 24 draws (about 26,5M). Can anyone help me, please? Thanks!
