Hi Pete, I saw that one and was a little tempted but decided that, as I already have 2, I would give it a miss.
You are right that it is a type that was seen more often 10 to 15 years ago than it is nowadays.
I ought to do a count of the Bramah 26a's from my 5 year study period covering that period; hopefully will get round to it one day, but haven't done too much work on 1858's yet as just so many coins and loads of varieties!
