What Autococker body is this?

What Autococker body is this? See notes below the pictures....











Info:

1. Pre2k front block specs
2. Not threaded for an newer RVA
3. Mainbody itself is approximately 1/4" shorter at the rear, than a standard body
4. Underside mounting holes match the spacing on my other full size pre2k AC body
5. Slide in RVA would have to be 1/4" (or so) shorter than a standard one
6. How would the shorter movement for velocity adjust screw affect adjustment?
7. Was it originally set up for a Sheridan type adjuster/spring/hammer? Did those have shorter RVAs?
8. Could it be threaded for a newer RVA? Would that work if it was?
9. Serial number is 28905.... 1995/1996?
10. Wait a second.... The holes in the slot on the right side are threaded... A different eye system? Sandridge?

Thanks for any info.......
