My thanks to all for your speedy, and I am sure, sound advice.
I have some high quality (and therefore large file size) photographs of each object and pairs of objects if anyone is interested. I think that I am unable to attach these as a post on this site due to file size restrictions but if anyone would like me to e-mail them direct, please let me have an address. Tiggie would this help your father please? If I had an idea on value it would help me to decide the best course of action as regards sale.
I remember as a young boy (50 years or so ago!) being taken by my parents to Mr Komaromy's house in Shirley, South Croydon and watching him work. It was a jaw-dropping experience that I will never forget - he appeared to create almost without effort - a true master at work. I also recall him saying that each piece had to be oven fired and that many of his creations were destroyed in the process.
My grateful thanks once again.
