Carter B&B ID

All
I got a Carter Ball and Ball carb and I can't find the ccrb number to order a rebuilt kit. Here are the numbers I could find on the carb:

On the side of the barrel 6 1697
On the top of the bottom plate 1-1746
On the bottom of the carb 1-1707

There is no tag on the carb.

thanks
