It may be the company I keep, or my Yorkshire birth, but I have both bought (to use) and sold (written off car ) part-worn tyres, and have also used both "new old stock" and 2nd hand parts to effect a repair at times.
However, to pass off old as new is fraud, and I'd not want to use anything other than new and unused in any paying job without the recipient fully understanding and agreeing to that being sensible.
I'd also be very wary of an MCB of unknown history, although in practice I suspect most are very lightly loaded. Things that are easier to inspect or have a lower price of failure, like glass domes for lamps and funny shaped springy fixing clips for downlighters are more sensible candidates for rescue and re-use from an old one.
