Lister Dating

Chris, All that David's letter said was Reeves Of Bratton were in business until sometime in the 1960's and took many Lister engines. Nothing to indicate the business they were in or what the engines were used for.

Stu.

if your engine number begins with 1/ or has a number with less than five figures, it was built after 11/3/1946.
because at that time engine numbers had reached 199999 and the decision was made to introduce a shorter numbering scheme starting with 1/1000. this system continued until DECEMBER 1951 by which time engine numbers had reached 1/77820.
At this juncture a further change was introduced because from 1952 onwards every engine number began with 1 at the start of each year and to avoid any confusion the SPEC.number was arranged to give the year of manufacture of each engine.
So for example DH2 was manufactured in 1952,DH3 in 1953, DH4 in 1954, DH10 in 1960 etc. hence an engine bearing the following number-281 DH5 was manufactured in 1955.
The majority of engines built from JUNE 1948 onwards were built at WROUGHTON,near SWINDON, production continued until about 1964.
Fortunately a little more information has been made available and enables the previously produced dating guide to be extended to 1958.
a final point concerning the reading of SPEC numbers on the later engines.
Instead of DH3..you might see DR3 or DZ3, so to avoid any confusion this small list may help our forum members in the future

SPEC...DR= R means radiator cooling.....
SPEC...DZ= Z indicates REVERSE rotation..however to add to the confusion..R was often used on earlier engines...
SPEC...DK= the K Stands for kerosene......
SPEC...DH= H..of course meaning hopper cooled......
SPEC...D2= sometimes used to determine output...IE..2hp.....

If your SPEC plate is missing from your engine you should be able to find the number stamped on the flywheel crown......

hope this helps some of our members....

I have recently purchased a Lister D type petrol engine, 2 HP, 1000 RPM, S/N 2814.

Would you be able to provide information on the approximate year of manufacture?

Thanks in anticipation

ect....

Do you also have the spec number of this engine? I think it is one of the last years.
Let us know everything that is on the brass plate.

The brass plate has on it:

No 2814D2

Spec (blank)

HP 2 RPM 1000

2814D2 is your serial number and spec number combined.
It is serial nr. 2814 and spec D2, and is built somewhere in the beginning of 1952.

Thanks for the information
