thanks Blacky
i have emailed the company.

I found this guy in Australia who has 20 pages of stuff on ebay.au
i guess these parts are probably made in Korea.but if you are desparate for spares, he is worth a try. ebay rules means i cannot get the name of his company or an address, but if you type in Parkeeparkee on ebay .au his pages come up. they are in no order so suggest you go through every page. i found gear cogs on page 21!!. shipping from australia is quick, 6 days to get to London, then customs want money for import duty. God knows what will happen to imports from europe when we leave brexit. i huge mistake i think
