    Looks to be an early experimental L23 APFSDS-T round before it was adopted and type classified based on the stenciling, purple stripe and date code?

    PS: Nice score!

    Thank you for the help APFSDS! , I'm getting pretty good at finding unusual ordnance related stuff.
    Correct me if I'm wrong but from looking at other experimental bits I belive the purple stripe can be an experimental modification to the APFS dart ?

    Tim, to my knowledge, I believe the UK uses purple to indicate experimental ammunition. In this case, I personally cannot confirm that the experimental designation concerns the sub-projectile dart or its sabot. Being that it is an early experimental L23, I would guess that the entire projectile was considered experimental until it was fully adopted and formally type classified as the L23? Your round was probably designed for testing until all the quirks have been worked out? I have seen a few experimental L23 APFSDS variants over the years manufactured before the final mod was adopted.

    It is an unchanged original XL23E1. Had there been any changes it would have become E2 and any subsequent changes would have become E3 etc. Purple has indicated experimental ammunition through several marking systems and is still the same.

    Just noted that your version has a hand written weight of 17lb 7.2 oz. The stated weight of the production L23 version is given as 7.89kg or 17lb 6.30z - a shade lighter than the experimental version.
    any live or dug ordnance. small arms ammunition etc in my posts have been dealt with accordingly

    Thank you everyone for the information! I've attached a picture of the whole round , the " case " isn't technically correct but I think it's unlikely I'll find the correct case for it

    Sorry for late entry to this thread. Just joined. The XL designation indicates that the projectile was from the period between design freeze, and full approval. The procedure was that at RARDE we used an 'in-house' designation during development, in this case C type. A type and B type were 110mm. the letter was followed by a number for the sub-projectile/ a number for the sabot, so C1/1 was the first 120mm APFSDS. At design 'Chill' materials are firmed up, and at 'Freeze' the whole design is finalised, and marking and nomenclature applied for. Hence XL23E1. This was followed by exhaustive approval trials, and at the completion of these the designation was 'upgraded' to L23A1. The 105 round was a Royal Ordnance private venture type H1/1 as a follow-on to the L64.
