Hello Mod BB and Dee Bee
I do feel this post and BB's observations have increased our knowledge
about this time when production was moved from Adelaide to Brisbane.
There is now evidence (in matching the Briggs Code) that Rover
originally painted the first Rover 45s in hammertone - and a darker tone
from the last Adelaide machines too.
I'm less sure the worn cutter sprocket necessarily means 'serious work';
given the good condition of the other sprockets. It may be that was a
result of poor maintenance of primary chain tension. That seems to be a common
problem with manual chain tensioners: too loose and the sprocket wears; too
tight and the bearings wear...
This will be an interesting one to follow, and you are in the best
of hands with BB's advice. I would like to thank Dee Bee for the
great images of the maker's plate and the engine id.
I really like the idea of a father/son project.
I have seen many rewarding outcomes from this.
It's best to start simple before the Bugatti Royale project.
