Missing Calculator

Did anyone pick up and old black Casio calculator from LT1 during Physics consolidation?

I've been using the same calculator since my Secondary school days and I never learnt to use another calculator. Therefore I am now much handicapped without this calculator that I'm so used to. Mr Simon Tan picked up a calculator from LT1, but that's not mine, so maybe someone took it by mistake. Please let me know if you have any information about my missing calculator. =(

Many Thanks.
