    Does anyone possibly know the maker of these old limbs I bought online from the UK.....
     
    Info required for old laminated limbs Fbfgk0zr.svt

    The black one has 77lb @ 16" marked on it, while one of the white ones states it is 70lb @16". I'm assuming the 16 inches is the length to latch, and guessing it is measured from the back/centre of the limb/ mounting, or the limb mounting point in the stock?

    The black one is in great condition.

    The fiberglass on one white one has started to delaminate from the wood core at both the string nock, and close to the stock mounting point. While the fiberglass outer laminate on the other is showing signs of minor splintering.

    Thinking of gluing and clamping the delaminations with 24hr epoxy, and maybe running the same glue, or polyester resin into the splintering glass... and then binding entire limb.

    Any thoughts appreciated.

    Look like home-made.
    I have a book with instructions for DIY fiberglass olympic bow. If one applied the same instructions to a competition target crossbow, results would look like that.

    Thanks mate.

    I'm going to use  two part epoxy and clamps for all the repairs including the splintering f'glass face, and temporarily bind with electrical tape until I'm confident (through testing) that the 16" from limb mount to latch is ok.

    Concerning 16" draw and assuming these are competition bows.
    IAU rules allow maximum power stroke of 300mm
    so intended brace height is probably somewhere around 4.5-5 inch.
    String length must be less than 900mm.

    I didn't know that they were all different thicknesses at the center section of the riser.

    The two white ones are 25mm, and the other is 30mm at center.

    Thanks for reminding me of these, must do something with them soon!
