First things First, Welcome to Rootschat.
I have had your request in mind since your original post back in February, with the intention of "Calling In" next time I'm in the area with time to spare. Having never been there before and that the local schools are on their Half-Term break this week I thought it wise to phone them to check they were open today. Just as well I did!
They're open to all: Okay. But you need to make an appointment and give notice of what you'll be asking for.
Just as well I phoned.
It'll be a month till I'm next in the area, with time on my hands.
You haven't been forgotten, well not quite.
Ohh, bye the way, they don't permit photography, and their on site copying is 35 pence for each A4 size sheet.
