Hi..... I've collected, bought, and sold many many pieces of cloud glass over the past 27 years..... As long as this is a genuine and much rarer 14.5 inch and not the slightly smaller version... and importantly being a complete 3 piece set I would not feel it all exorbitant to pay up to £275 for the modified orange and if well marked, as the unmodified can be, then £350...and poss a little more...... A beautiful and impressive set..... If you do buy it please load up some photographs here....
Hope this helps
Gareth
