Thank you very much for the reply and your interest. Also received your PM. There is a fair chance that 20763 has been junked in Vientienne which is an undignified ending for something that gave such great service over many years. If you come across anything further and care to pass it on I would be most grateful. I have even promised myself a holiday to Laos with the express purpose of obtaining the serial number plate if 20763 is junk. It would look nice mounted on polished wood. Thanks again, all the best.
