how to identify shimano 105 5600 brake/shifters

[arndogg]

i purchased a set on ebay, and it was advertised as a 10 spd double.

I ended up bringing it to a shop to install, and when I went to pick it up, the bike mechanic said that i have 9 spd shifters.

How can I tell if I have 5500 series or 5600 series Shimano 105 levers?

pull the hood back, it says right on side of the shifter body. or, use the googles...it's not that hard. or, count the clicks...8=9spd shifter, 9=10spd shifter

Just curious: so did he install them anyway and leave you with a bike that has 9-speed shifters and a 10-speed cassette? I'm collecting "stupid mechanic" anecdotes.
