Another one of my Flea Market buys today was a French 20x139 Steel case, for the huge cost of 50 pence.
The headstamp is: “CN MIT 20 F1 13 -MR- 76”
Am I right in that “MR” is Manurhin, and “76” is the date?
I presume “CN MIT 20 F1” is the designation number and “13” is the lot number. Is this correct?
Primer is a screw-in type with a brass cap sealed with green annulus, and has 3 semi-circular holes for the insertion tool. It is marked “SF 4 75”. Am I correct that this was made by SFM in April 1975?
