Thank you all so much for your help! It's all so interesting...
@magpie - is it usual for there to be handmade ones? I had wondered why it wasn't quite the same as the others I'd seen. Does that likely mean that the person who gave it to her wasn't actually in the RFC? Why would they do that? Sorry for all the questions I'd just love to know more and so would my Grandma
@monty - actually there is! What does that mean?
@Bill A (and everybody really) thank you for your warm welcome and great info!
