Thanks, Philip. I think I'll have 1888 of 1940.
Now I've just got to order some nameplates. I'm going to have British naval heroes of the 18th/19th century as a theme for my fleet (fleet, get it? OK, I'l get me coat.. ) . I've already got one Peckett named Lord Nelson so this one is going to be Admiral Duncan.
The Peckett works list is unusual as, apart from the gaps in works numbers, the dates are not always consecutive. I think the reason for this is that locos were built, or perhaps started, to their standard designs in batches and allocated works numbers but not actually completed or sold until some time later.
Consider the list between the last two X2s:
1869 was ex works 3/1934
1870/1 ex works 9/1934
1872 ex works 1/1940
1873 ex works 6/1934
1874 ex works 12/1935
1877-9 ex works 10/1934
1880 ex works 5/1935
1889 ex works 12/1934
1890 ex works 1/1936
1891 ex works 2/1940
after 1891 there were 57 locos with ex works dates of 1935 to 1939 before the next with a 1940 date - 1969.
So for your theoretical X2 a works number of 1888 with a date of 1940 is possible, assuming like 1891 it was started, allocated a works number but took some time before a customer was found, or from the above you may perhaps consider a date in the mid to late 1930s more suitable.
1889 was ex works on 31/12/1934, so may have had 1935 on the plate although clearly it must have been built in 1934. It was minus works plates when I saw it at Marine Colliery, South Wales in 1975.
