I'm a little dubious about the No5 shown for two reasons. First, after having seen a thousand or so No5's and even knowing the Fazakerley reputation for abysmal engraving (and workmanship, but I won't dwell on that.....), I haven't seen real Fazakerley engraving this bad. Secondly, the poor image we see of the right hand lowered bodyside looks to me as though it's uneven....., as if it's been done after it was hardened and the cutter or file couldn't cope. Maybe it's camera angle and all that but a picture of the right hand side should tell us.

Just my two pence worth...............
