Talk:GWR No. 12

12=13?
Were 12 and 13 identical? If so, the "total produced = 1" in the fact box is a bit misleading. --Roly (talk) 11:04, 6 June 2013 (UTC)
 * According to

 * There were other differences such as brakes and train heating, but it's apparently unclear whether these differed as delivered, or were the result of later modifications. -- Red rose64 (talk) 15:49, 7 June 2013 (UTC)

Hugh Llewelyn
Searching Commons for Sentinel 6515 bring up a couple of images, apparently of this loco, but captioned 'Hugh Llewelyn'. There is no mention of such a name in the references. Is it the same loco with a different name, or has a different loco been confused with 6515? -- Verbarson talkedits 20:54, 13 April 2022 (UTC)


 * Am I short-sighted or what? 'On closer inspection', as they say, it turns out to be the name of the photographer. -- Verbarson talkedits 21:05, 13 April 2022 (UTC)
