If you can't fine one anywhere on eBay or gumtree that's enough to say rare I would say... Also as I am in marketing and advertising so can't help it as it comes naturally to upsell...
Anyway I think this post is about few weeks old now so time for you to let it go and just move on with your life.... You can do it, just one step at a time though!
Rare or not who cares it sold and that was the goal
Night, night and God bless
