Lister DK Age

[djvdberg]

Hi Guys, new here, thanks for the add!

Busy restoring a Lister DK, and curiouse about the age, couldn't get any matching number from any reference I looked up online, can someone please help identify this model year?

I'm from South Africa don't know if the numbers was maybe any different here?

No. 12491 DK2
Spec
H.P 2 R.P.M 1100

Thanks!

1952

Agreed, 1952.

In '52, Lister changed how their serial numbers worked; from a straight numerical sequence (possibly followed by some letters/numbers to indicate features such as reverse-rotation, marine use, etc.) to a carefully designed - and yet possibly utterly confusing - system which is:

Engine No | Type | Variant | Year

So yours is engine no. 12491
It's type D
Variant is K
Year is "2" - counted from 1950 (even though it only started in '52) = 1952.

Unfortunately the CS range were indicated as "51","61", "81", or "102", "122" etc. which can make them easy to mis-identify as an older engine...
