On Czech 7.9mm “Z” headstamps for the first 3 months (lots?) of 1937 the numbers also appear as 1, 2 and 3 as opposed to I, II and III. These are supposed to indicate that they were for a contract for Romania.
I was looking at the todocoleccion.net website and ran across a headstamp I have never seen or heard of before. It is month/lot “4” of 1938.
Has anyone seen one of these and do any others exist that are not with roman numerals?
