I have four cartridges, 7.65 x 54mm Belgian, all made by Kynoch in 1933, all with headstamp K33 7.65. One Tracer, red tip on CNCS bullet and red PA, One AP, green tip on GM bullet and green PA, One Incendiary, blue tip on CNCS bullet and blue PA, and lastly, One Incendiary, blue tip on 2-piece CNCS bullet and blue PA. All primers are flat brass cup.
These were obviously made on contract for ?? Argentina ??
Are there other dates or headstamps ?
Peter (enfield56), do you have any drawings ?
