No

Need to see internal venturi to be 100% sure

I wasnt sure about them, i thought they might be due to the big plug where the jet is... but the bowls are not like the ones on my old A1(uk)...any idea if they were stock in the US or are they from another model?

Yes! I'm 99% sure they are.
They look just like mine

Here's a pic of some smoothbores to compare (bottom pic).

I would say they are smoothbores.
Smoothbores have the small square recess,just above the bowl flange.

Yes! they used that same bowl for the smoothbores.

The main clue to smoothbores is the square recessed casting on the r/h side with the drilling blocked off with the ball bearing.
