When did Standard 4s gain double chimneys???

[SteamingWales]

Hello all

 

Currently researching a layout circa 1958-1963 and was wondering the approximate dates when the Std 4 4-6-0s received double chimneys. I've managed to find a list of all the locos that were rebuilt with double chimneys (below) and a couple of dates too. Also been looking at photos on Colour Rail and similar but finding it difficult to work out dates from that. I'm mainly concerned with the WR allocation so 75065-75079 I don't really need to know about

 

Locos rebuilt:

75003, 75005, 75006, 75008, 75020, 75026, 75029 and 75065 – 75079

 

75003: 6/62

75005: ?

75006: ?

75008: 9/62

75020: 7/62

75026: ?

75029: ?

 

Any help with the other locos would be much appreciated

75029 was the first to get one in June 1957. It was quite tall and somewhat ungainly, and subsequently other engines modified at Eastleigh received shorter chimneys with 75029's being eventually replaced. I don't have any information on when the other engines you list were fitted.

Edward Talbot's book on the Standard classes says the SR ones were done 1960-61

75003  12.59   75004 10.10.62  75005 9.2.62  75006 16.12.60  75008 12.2.61  75020 28.11.58   75022 1.59

75026 25.6.62  75029 20.5.57 (experimental) 11.2.60 (production version).

Hope this helps.
