Sucks Graham. I know what you're feeling. Back in June I had my Think Tank Logistics Manager and a couple other bags stolen . I had gotten home late and was tired, so I grabbed my F-stop gear back pack ( THANK GOD! ) that was in the front seat which had my entire Phase One kit and 4 lens's, locked the car, in my driveway, and was going to come back out in a few to grab the rest of the stuff. Needless to say, I popped open a brew sat down and processed the days work and forgot all about it. The thieves nabbed the big bag which had Nikon, Broncolor gear worth just north of 30K. The police said most likely kids and they work a neighborhood checking door locks and popping locks. I did find out the policy I have had a couple of special riders that covered like 5K in additional items that I lost that were not on my policy.
I hope all works out for you. That feeling of violation is horrible and really never goes away though the check will help.
All the Best
Don
