G'day Swiftdevil,
At least a couple of Owner Manual versions are available for download in the ODK Scott Bonnar Manuals section
HERE.
Note that this is a paid subscription area - instructions on how to subscribe are at the top of the page.
I think that the first doco on the list there could be the SB45 Illustrated Parts List, but I don't have the access to check that for you - CyberJack may be able to help with that.
