Another long shot. You could pass on the serial numbers to the airports (customs) in case they try to sell it off cheap to a tourist. Lots of this type of gear is taken out of the country.
Peter,
Why don’t you put up a wanted to buy advert on all sites for what you had stolen camerawise? (Obviously not stating yours was stolen)
Maybe the person who stole yours will be online looking to see what it’s making on the sites and see your add and make you an offer that “Will stand out”
Maybe then you could meet him in person to buy and get it back?
Just an idea but i have a friend who had a Canon XL1S stolen from his house last year and had it back within 2 weeks by doing this..
