MSFC(?) technicians are seen working inside the S-IV stage of most likely SA-1.

The whole apparatus inside the stage looks like a platform, with a ladder leading 'up' to it, when the stage is in its vertical position.

Two H-1 (I think) engines can be seen in the background to the right of the S-IV stage.

Is that possibly an early cordless drill in the right hand of the gentleman on the left?

 

 

Probably the same S-IV:

"MSFC tested the S-IV dummy stage for the SA-1 flight vehicle May 20-25, 1961. After successful testing the Center began to ready the stage for shipment to Cape Canaveral."
