    Bonna

    Picked up a Bonna at kempton... bolt action military trainer type jobbie, 4.4mm ball repeater with Mauseresque woodwork. Quite similar internally to the Haenal 49a I already have, which is handy as I knew how to repair the missing pellet probe and get it firing Obviously quite low power, even more so that the Haenel - not surprising as the Bonna bolt has zero mechanican advantage, unlike the schmeisser rocking bolt of the Haenal..

    But what model is it and how to date it ? it has "31" stamped on a few parts ? Also when were they made ? Looks just like the Mars, but I gather these are newer ?

    Google isn't helping me much... all I can find of real use is from Frakor in this site:

    "there are 2 models, a model 115 (100shot) and a model 98 (75 shot) both use the 4,4mm ball."

    Mine is the full length

    So no idea what the 31 stamped everywhere is !

    TIA,

    JB

    Could I have some pics for the gallery, please?

    Thanks for that Danny, wondered where the Haenel "Sheibenkastan" I just acquired came from.

    Did some pics.

    It's a bit tatty, but i think the pix make it look even worse

    The top woodwork is non original, but I needed something to cover the BB "hopper", and this was close. The original goes all the way forwards to the steel wrap-around bracket.
    Bottom pic shows the massive counter-bore, which extends half way down the barrel.
    3rd pic shows the gun cocked, held on the trigger sear, ready to fire.
    Power is very low as there is no mechanical advantage in the bolt system, a (thankfully) weak spring, and a 4" long pellet probe / transfer port

    I like that! It looks like its been to Stalingrad and back. You just need to cut some teeth in the bolt, screw on a helical gear and fit it with a HW80 spring. The cock it using a cordless drill and you'll be shooting holes in dustbins in no time.
