At The Surrey Steampunk Convivial, there have been several suggestions for setting a few Steampunk World Records:

 

The most hats in a hat stack - Steve Jones

 

The most hipflasks concealed on a Steampunk - Spy Mistress General

 

The most Steampunks attending an event - Cubinoid

 

(Now, we all know that any record attempt for this will likely be beaten at some point...but as there is currently no record set, it will give everyone attending Convivial a chance to be a Steampunk record breaker!!)
