Wickham or another?

This sludge pump is attached to a listed D could anyone in the know confirm what make it is? It has a david brown rodicon..er..think on it, I presume that is just some sort of 'turny thing' (lol) for changing the drive, is the actual pump just some generic brand or is it a wickham? I next to nothing about sludge pumps and to be honest never really felt the  urge to learn more about archaic sludge pumps

Any help would be greatly appreciated

That engine is a Lister LD1 I think, not up on my lister diesels, a quick google search confirmed my thoughts, the drive to the pump, would that have been a rubber coupling connecting the 2, nice looking pump sorry cant help on what make it is.

That ok thanks for your help, Chris
I have little to no clue what it is either, i have done so googling, but it doesn't get me very far, I know it works and could empty the canal, but I don't really get many canal emptying jobs
