Hi Jordan,
Thanks so much for taking the time to look, that’s very kind. I’ve sent a message to the seller to get some more details and I’m awaiting a response. That is essentially, as far as I can see, my only option! Hopefully it’s all legit and problem solved but I’d love some alternative options as I’ve had some problems with ebay in the past.
I’m just surprised to discover that Maxon don’t allow you to purchase any backdated items from them.
