    Well, it would be.
    I have gone through range tables for the 122 howitzer M38 from 1946 to 1989, manual for the H38 howitzer, Overview of ammunition, Manufactured ammunition overview and I have found no trace of Czechoslovak manufactured illuminating projectile.
    The only ones are S-462, S-463, S-463 Zh and 3S4. The manual Del-51-27 lists also a Romanian manufactured round BC-463M.
    I will try to look for more info.

    But in general language the round would have a designation 122-EOs-H38 and projectile 122-Os-H38

    The Former Soviet Union stuff is difficult at times to figure out without actually seeing the rounds. Only then can you find the manufacturing codes and figure out where they were made.

    So you think this I a Russia round used by Czech then?

    Also is there a place to get a copy of manual Del-51-27?

    I am pretty confident that I will find the answer next week in the archive.

    List of produced ammo for 122mm H / 38; 122mm H38 / 74 ...Czech licenc product (series and numbers of licensed munitions) is certainly not available on the Internet today. If I ever looked for and made an inventory of the produced pieces, I would look at the then plants capable of machining the mechanical parts of the ammunition. The licensing production drawings that we have certainly received from the USSR had to redraw some of our standards, and besides, it had to be a general Ilum. program.

    Hi, here is the promised info on the illumination round:
    Designation: 122 mm EOs (122mm separately loaded illumination round)

    Test series(lot) 0/61
    Number of rounds: 1626
    Projectile: manufactured by “fut” (Adamov) with Fes driving band according to blueprint no. 201230
    Fuze: T-7 – imported from USSR
    Cartridge case: drawn steel, blueprint no: Mu 40312 manufactured by “aym”
    Powder charge Nc tp (nitrocellulose tubular powder) manufactured by “nma”
    Primer screw:KV-4 manufactured by “gts”
    Flare 102B
    The round was assembled by “gts”
    The test series consisted of:
    1474 live projectiles
    52 inert projectiles
    100 projectiles with live fuze and expelling charge and inert flare

    An undated document, written after 1973, says:
    Czechoslovak production ended with the test series 0/61 gts, the 122-Eos-čs was not put into serial production. Supplies come mainly from import, especially from the USSR and two lots from Romania. Romanian ammunition is manufactured under soviet licence.
