Makers marks, Numbers & Letters

[Taz]

Here is some interesting new info from Victor on his award.

Order of PW-2 #101278, which is currently in my collection, has a very small digit '1' on reverse, and not the cyrillic "Y", as stated.
The height of digit '1' is 0.7-08 mm, as opposed to the usually seen technological marks of 1.3 mm in height.
Such "short" digits are seldomly observed and therefore, rare.

I'll correct the info in the second list.

Eddie.
