When is a Lister not a Lister?

[Schwen]

I came across this advertisement - it seems there is a difference of opinion as to whether an Indian made engine, apparently produced from original Lister moulds, is actually a Lister or not. That this engine is branded "OMEGA" suggests not, despite what the seller claims. Anyone heard of these?

That’s a bit like claiming those Indian taxies are Morris Oxfords!
Morris Oxfords were made by Morris and Listers were made by Lister.
Anything else is just a copy.

Molds are only a small part of the build.  What was the iron recipe used in the pour?  What machine tools were used for the finish work?  Who did that work? Who did the final assembly?  Unless it was in a lister factory with lister tools by a lister employee, then it is NOT a lister.  If you ever see one of each set side by side, the difference in the workmanship is immediately apparent,   Hence the term "Listeroid"

I call the Indian engines "Lister pattern engines" The exception were the Indian Rustons that were built under the watchful eyes of Ruston engineers. Stover and Brownwall also built engines badged as Lister.
