As Alfred Davies' grandson, I was interested to see your thread, which you almost posted on his birthday! (25 February). As you may know he started the firm when the Aeolian company folded, as he had been in charge of the organ section. Presumably they continued in the same premises but I do not know for sure. They moved to Northampton during the war and my father jack joined the firm when he was demobbed. I remember the collaboration with Forsyth Grant being established in the 60's when A E Davies took over the tuning work for GDB. My father and Maurice FG emailed firm friends up to Maurice's death. I do not have much in the way of records as I think we sent everything off to some august body when my father died. There was an Ainslee trust which played a role in keeping the firm afloat in the 50's I believe. Jack Davies pioneered the combination of electronics and pipes: I have a set of LP's which he made as a demonstration of the capabilities of this new direction. A bit of a ramble I'm afraid which does not directly address your enquiries! Good luck with the rebuild, I'd love to see it when its done.
