Darlows may be gone, but at least the stag still remains on the building, peering at us through the branches. Courtesy of Google Street view.

Thanks for the photos Longknife. looking at them, I would have dated this gun earlier than 1936, although the British gun trade was still making similar hammer guns at that date.

I wonder if Darlows had it re-barrelled by Asbury in Birmingham. There may be a clue on the action flats if there are signs of an earlier set of proof marks, as well as the marks applied when it was proved in Birmingham in 1936.
