I must admit that I felt that this unit was too old for spares. Its
one that looks like a pot bellied stove, sits on 3 cast in legs like a
milking stool, with the motor vertical.
I also have a Hydrovane 4 still old but more modern, when I checked
the prices for bits for that I went all faint and sat down very
quickly <G>. £270 + Vat (No new Rotor body or vanes).
