An unusual stamp, presumably to comply with an export requirement that country of origin be stated, the first of which was the USA's 1891 McKinley Tariff, however I believe these to be later as they appear closer in design to the post WW2 '240 series' marks.
Condition is superb, several of them may never have been sharpened, The set didn't have a 1/4" so we have added a TOGA in similarly good condition.
