I like the pic is that what you call small cell hives?
If you mean my picture by my name, it's natural comb from a large cell commercial package of bees with a Carniolan queen. Some of the comb is 4.7mm
The regressed bees often build as small as 4.6mm and as large as 5.1mm
Here's a large version of the picture.http://www.bushfarms.com/images/47mmCombMeasurement.jpg
