    After Hercus took over the shaper from Douglas and it became the Hercus 270 shaper, the shaper vise remained the same, or at least almost identical.
    So, that could be a Hercus 270 shaper vise. That...

    Thanks to Bob

    Thanks Bob for supplying the Hercus 270 manuals to me also.

    I have aquired a 270 which is currently being overhauled. I'd be interested to know how many 270's are out there.
