I have been compiling a list of 303 clip makers and require the makers of the following and hope that someone can help or point me in the appropriate direction.
Mark 4 P&S, MB in circle, AS in square, MR with X in circle, JPjoined.
Mark IV S,
Mark III F, O (large circle),
Mark II with nib g (this is the old style)
Mark II with and without nib V, W
Unknown Mark B in circle, E in circle, C
I realise pictures would be ideal, but I don’t have all the clips, in some cases just a snippet of information.
