Calumet warranty on used sale now 12 months

[gramps]

Just had notification that Calumet are now offering a 12-month warranty on their used equipment sales - brings them inline with Grays, not sure if anyone else does it.
I noticed the following in their Warranty Terms 'exclusions' info:-

faults occurring to items where parts are no longer produced,such that the item cannot be repaired

Wonder how that works out, maybe a few months after purchase?
