Egg timer or timer

[nyah]

i invite people to find/take a picture(s) of the inside of an egg timer, preferibly one that is of a small egg or genrally small anyway. my idea is to try to modify it into a timer lock by altering the bell part as it is the moving bit. also if you can include the model name or manufacturer and how long you can set it too. prferibly one that last 4+ hours.
