Yes, excellent photo.
Apart from people thinking that the missing cylinders would make 71000 impossible to restore, when in use it suffered from poor steaming and heavy fuel consumption such that it was not popular with crews. Presumably this was why it was a lone member of its class. But as you say, and no doubt because it was a unique engine, it did have a mystical aura, and it was one I always wanted to see but never did. The thing about Barry though, and arguably for some one of the few the negative aspects about it, was that it contained mainly locos from the Southern and Western regions that were amongst the last to be withdrawn, like West Country/Battle of Britains and Merchant Navies, which in itself made others which did not fall in that category quite unique. Offthe top of my head I cant think of any ex Eastern Region engines other than 61306, but there were 28 Bullied pacifics. Similarly quite a few Standard Tanks, but every single one from the 80XXX series.
