Finished at £20,630, plus premium (5%) and handling charges, so another £1k or so.
Looking at auction prices (In Classic and Sport Car mag) for similar age 12/50s that wouldn't seem particularly cheap, but I'm no expert on Alvis, and don't know the difference between 12/50 and 12/60.......
I would imagine the insurer who consigned this one to auction will be reasonably happy.......pity I wasn't on commission
