    Default lightweight bolt/plastic versions of Chubb safe locks

    I am not bad on knowing lock model numbers, but on a lot of them if you saw them boxed and labelled they would be down as mk3 or mk4 etc which i have never seen a lot of info about.
    You don't see the lightweight bolt versions very often, but here are pictures of a couple, if you have any info on them, please feel free to comment.

    a 6K18

    Default

    and a 6K174 but this one has aluminium plates either side of the bolt head as reinforcement, whether this was a later adaption because the lightweight bolt heads were getting damaged or not, i don't know.
