Interesting project into the workshop this week.
It’s a 1954 ‘3-Star’ model, made in Melbourne. Still working on the specific model, but shouldn’t be too hard to find with some research. There are lots of Malvern Star experts.
horizontal dropouts 
Flat crown forks 
Interesting brake bridge
Seems to have plenty of original parts on it: BB, Headset…all under three coats of house paint.
First stop – sandblaster!
Let me know if you want another to work on. Happy to sell mine to u.
