Sorry Dawn, I've only just seen your reply

From PMs, I think oldbones is on the way to a solution .............................
What I'm hoping for, as per the linked thread, is that SKS can have a look for my chap in Abingdon and/or Reading prison records. I couldn't see a 'Help' contact on the BFHS site, and other matters mean that I haven't had a chance to look at BRO resources yet. Will try tomorrow.
