I found this thread
https://www.outdoorking-forum.com.au/forum/u...field_12-30_spare_parts?_.html#Post74056I don't know if the guy still frequents the site, but it could be worth sending him a PM to see if he had any success.
ps: is that a parts manual underneath the spare bits, if so can you take a pic and post it, as it may help others identify them.
