i cant scan or upload pictures at the mo me comps got viruses so its in getting formatted so im on an old pentium 3Could you post a photo Brightspark - the two Fortis vices and the possible all look a little different. Yours might be the connection between them.
Your vice looks like a mixture of the mystery Zardoz vice and mine. I think you have knocked the nail on the head there. Any idea of the date or history of yours?
I was guessing with the date of mine, but if it is Fortis chances are mine might be an model made before of after yours.
