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)[reply]

According to

Tabor, F.J. (1959). White, D.E. (ed.). The Locomotives of the Great Western Railway, part six: Four-Coupled Tank Engines. RCTS. pp. F8–F9. {{cite book}}: Unknown parameter |month= ignored (help)

there were differences in several details, including:

	No. 12	No. 13
Boiler barrel	4'10+13⁄32"	4'4+5⁄8"
Boiler diameter outside	3'1"	2'8+1⁄2"
Firebox height	4'9+13⁄16"	4'4+3⁄32"
Firebox diameter inside	2'6+3⁄4" & 1'11+1⁄2"	2'3" & 1'8+1⁄2"
Tubes	30 x 2"	30 x 1+3⁄4"
Heating surface, tubes	36.5 sq ft	27.729 sq ft
Heating surface, firebox	35.0 sq ft	26.700 sq ft
Heating surface, total	71.5 sq ft	54.429 sq ft
Grate area	5.1 sq ft	3.97 sq ft
Boiler pressure	275 lb/sq in	300 lb/sq in

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. --Redrose64 (talk) 15:49, 7 June 2013 (UTC)[reply]

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 ^talk_edits 20:54, 13 April 2022 (UTC)[reply]

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