Seeking to draw on the power of the information superhighway, I'm trying to finally get to the bottom of the issue surrounding the hooded ARP lamps with the label:
M.O.H. Code No. WD 3051
M.O.H. Order No. S1/52/B1
On a forum I read many moons ago (and which I cannot currently locate online) someone commented that the M.O.H. designation was a post-war designation. Can anyone confirm or deny this?
UPDATE: a number of people responded to this question on Facebook. Currently the consensus points to these being post-war lamps.
