Yes, this was the UK quad produced for just the Irish market, The Irish who thought a semi clad / nearly naked Shirley Eaton was too racy - even if Sean was in front of her and nothing was obviously visible.
So instead, the Hand Quad was produced.
I got mine from Ewbanks only last year. It was around the £4.5k mark, which I think is about right. Unbacked, and in very good condition, albeit the folds on the thicker paper stock produces more prominent white lines on the matt presentation than normal. More like the effect on the gloss US 1 Sheets when machine rolled and the gloss cracks a little.
