old thing quiz

looks like i will go with the flow. icemoon ends the year with a 'where is this building in s'pore' quiz, victor koo has his usual 'old building' quiz and chun see's is 'can you identify this place?'. my last posting for 2011 is a quiz based on something old.

senior citizens, with the exception of icemoon, should have no problem providing the answer to this quiz but those who belong to the post-65 generation may not have seen this device. it was in use between 1948 and 1961. of course, you can still see them but they are indeed rare.

quiz questions:

1 what is the almost rectangular shaped thing in that slot?

2 what is the proper name for it?
