Thanks for the mail - nice to hear from you again. Yes of course I remember you, and coincidentally I was speaking to Graham and sending him a mail while down-loading yours. I am trying to get him to sign up to the Mailing List.

Guilty as charged.

Yes of course, although my grandmother replaced the one on my car years ago with a bronze casting, and I have never been inside it. So I am not a very good person to ask. I will contact a friend who lives fairly close to you who will probably be far more use than me. (JH - would Ivan be able to help? I don't know where he lives)

Mine also has a flange connection, but I know that it faces in a different direction from the original. it is quite possible that there is more than one version as no two 2-litre Lagondas are identical (they seem to have been built that way).

I am sure there is some sort of thrust retainer. I have seen various articles over the years about water pumps, so there is a lot of knowledge out there about these things. Try Peter Whenman at www.vintagecoachworks.co.uk who fettles Lagondas professionally.
I'll contact you again later direct.
