im told its pre 60,s??,, and originally would have had some hydraulic clamp/vice fitted,that is something id like to get a look or an image of it back in the day,for a desktop its fairly heavy duty.
it would be great to get a manual to this and some history on it.
also can anyone tell me the appropriate name for the locking clamp in the image,ive typed in everything from toggle clamp to locking clamp and cant find another

I would just call that an over centre locking clamp!!!G.
