Unfortunately, left my manfrotto 055cxpro3 + Markins Q10 outside a cafe after a landscape photography trip in Snowdonia, uk.
Only realised 2 weeks later.
Police did say, that even if it had been handed in, because I didn't have my name/number on it, I would be unable to positively identify it as mine, so they couldn't have let me have it anyway.
Insurance has paid out, but do any other people mark their stuff? (less excess of course)
