As we know, any vintage Monaco derivative was made in very small numbers compared to the 'Limited Editions' of 5000 or so of today. Maybe he has seen the 1133G/G described as 'rare' and just mistakenly assumed it was a limited edition. It doesn't look too bad, the photo's are rubbish though. The case is ok, a few scratches but it still looks like it has quite crisp edges. The crystal's on the wrong way which I think from a 'dealer' is a bit of a poor show...
