The next job I tackled was the seat, unfortunately the original was lost and a shabby replacement was in its place. I picked up a very clean one from e-bay and set about dismantling it.

I ordered replacement screws, rubbers etc and sent the solid base away to be powder coated. The result was excellent and the seat re-assembled. I'm very pleased with the result.

Top Tip: The seat foam was tired looking after 30 odd years and rare as hens teeth so I cut pieces of new sponge and inserted in the seat drain holes, you'll get the idea..(Thanks for that one Shane)
