Like a lot of collectors, we tend to hoard spare parts for our machines. You never know when you'll need a particular spare part, and sometimes you hang on to it in case you never have the opportunity to buy it again! However, hoarding parts keeps them out of circulation, potentially making it difficult for others to return non-machines back to operation. Plus, keeping boxes of spare parts squirrelled away in boxes forever makes for a messy workshop!
Parts that are surplus to our needs, unnecessary for maintenance of our own machines, or simply better off in the hands of others, are listed for sale here.
