Super Jet Help identifying a Mikuni SBN carb (44mm or 46mm)

[96superjet]

Bought a ski that had a set of "silver" colored Mikuni SBN carbs. Looked at the SBN manual and it appears that both the 44mm and 46mm versions came in silver (see attached image). I don't see any discernible model or part numbers on them.
Has anyone ever taken a set of calipers and measured the opening of either size carbs?

I'll upload a pic of them when I get home. ---> OK So here are the updated pics and stagesrt4 was correct. It appears that the base opening of each carb is approximately 1mm larger than it's stated size (see pics below)

you need to measure the bottom of the carb

Post a photo of the bottom of the carb. The machined step at the mounting flange is a different depth between the 46 and 44.

Reviving this as I need to identify a set of carbs 44mm or 46mm.

The actual bore where the butterfly sits is 1.813" or 46.05mm. So I'm assuming these are 46's?
