How can I identify the age,value etc. of leaded stained glass window panels that I have.?

I have five panels,which came from a house in Edinburgh and fitted a bay window. they are leaded and have primary coloured glass, all of which appears “dimpled” . The colours are vibrant and still in very good condition. They fit at the lower half of the window behind the original window glass. I have had them for many years and feel they need to be rehoused where they can be seen in their ful glory, but need information on them first.
