Single barrel holley carb identification

Please help, I'm restoring an older jeep f-head, it came with a Holley single barrel carb with the following numbers: List 2273-2 AND C2TE-9510-L. On the base it has 12B 1958. On the barrel it has M5. and finally on the area with the holley name it has 6R 2198 B. I would really like to find out where this carb came from, are rebuild kits still available, and how it works so I may make simple adjustments.
Thank You very much - Kevin
