According to some research on 29mm smoothbores there are several factors that will point to wether or not they really are the smoothies or 28mm stockers.
Z1 outlines it pretty well, noting the the differences in the top cap. 29's will be more round like the stock 26mm vm's and will be tightened to the body with 3 phillps head screws, not 2.
Also the float bowl will have a 17mm drain bolt, however some early models will have a drain screw angled to the side.
Saw these on the bay (auction over now).

They "measure" 29mm on the head side, and 39mm on the intake, which seems to be right.
Also they appear to have the rounded cap and the 3 phillips head screw pattern on the cap.
The one thing is the accelorater pump. Quite a few of the 28's were pumpers, but there were some 29's albeit rarely that had the kit installed.
So these 29's?
