An update...
Today I striped down the original seat and seat post with clamp. Once all broken down I examined each part for damage or problems and other than a little bit of light rust at the top of the seat post everything was fine. I have placed all the parts individually in gun wash to soak, remaining all the dirt and deposits that had collected of them. After 20 minutes I removed each part and scrubbed them with an old toothbrush before having a second wash in fresh gun wash. After all parts had received the same treatment I patted them all dry. I was really pleased with the finished effect as the original paint finish has developed a quite nice patina from the last twenty years or so.
The seat post was gently sanded on the top to remove the light rust damage and I applied a coating of clear 2 pack clear lacquer on the fresh top surface of the pipe. After placing some medium machine grease in the bottom edge of the seat post and frame I refitted the part and tightened it down. I used a new 316 marine grade stainless steel bolt, washer and dome nut to tighten it down on the seat post. The original fittings were looking very rusty and a little sorry for themselves.
