Fake British No4 MK1 cruciform Bayonet?

[Peter Laidler]

NZL1A1 coll. These are/were called 'stage inspection' marks. You'll occasionally see where a part has been inspected by a stage inspector and during a subsequent operation, half or part of the previous mark has been skimmed away by the next or or later machining op.

Our book of marks just names these as stage inspectors marks but I'll ask the old Apprentices if theycan identify any as these are the skilled blokes who all went up the ladder to these jobs and beyond............. ever onwards and upwards!
