Over many years of looking I have seen two 1890's with low 90 on ebay.
One of these was low grade, which I couldn't bring my self to buy, so I informed a collecting colleague.......and he bought it.
I found the one pictured below much more recently, and was pleased to acquire it for under £70.
I think they are rare.
By the way, I never did get any reply from Mike Hopkins relatives. The nearest relative was found by heir hunters to be living in Canada, and I asked the appointed Solicitor to pass on my contact details so that I could ask them if Mike's collection had formed part of the inheritance. This was because his house had been broken into after he passed away suddenly (in his house). Also, no one seemed to know if his collection was in safe custody, or in his house.
I wonder whether we will ever get an answer to that; it was a fine collection!
