Gents of the Wireless Expertise fraternity...
.... if WS No.19 sets have the following serial numbers:
65343
66769
67364
76342
82592
83570
97769
.... is there any way of telling which Mark of set these are (Mark 2 or Mark 3)? They are probably all sets of English origin, given the references that I have.
Thoughts, please, on this conundrum...
Thanks
Mike
