Attended an auction preview yesterday (Friday) and thought I'd share this - it's the catalogue cover 'highlight' for the Saturday auction and it appeared, on quick inspection, to be quite a nice example - no apparent gasket melt etc. and the service hands not unexpected nowadays. Estimate is £5k-£7k and believed to be from '71. I'm not affiliated with the seller/auction house and didn't know if it was poor form to name them on the forum, so I haven't (a quick search will surely find it). I will be attending to see where it ends up and happy to report back. Anyway, here's a few pics:

Thanks,
