Help for first project! Alcon Mark 2A water pump

Hello!

I'm a keen first time fixer. My wife bought me an Alcon Mk2A (attached to JAP Mk2 engine) for recent birthday. It's circa 1944. Have got it all in bits but in doing so have broken the impeller (which had a crack in any case). Have contacted lots of people online for replacement but haven't had much luck. Everyone keeps referring me back to Morris but they haven't been much help. Does anyone know of anyone who might have one or any info on compatibles? Any help much appreciated!

Have you tried Amos pumps this is their link, any chance of image of impeller as I have a damaged Alcon water pump impeller good, but do not know what model it is.

Hi Rich

Thank you very much for this.  It seems that amospumps have sold all their stock to Morris and they say they don't have any!  Crazy situation, I don't seem to be able to get any sense out of them.
If your impeller has a 3/4" (13mm) thread inner diameter and approx. diameter of 5"  (12-15cm), I will purchase it from you.
Thank you for your help
