I found the information in regarding to Saenara Bluebird in this website:
1962 Datsun Bluebird 312
Scroll down to 'A Daewoo Datsun?' group.
After Saenara collapsed S(h)injin decided to expand and they ended up taking over the Saenara factory and started building the Bluebird under the name of Sinsung-ho, which means "New Star".
