The 'typing unit' is much the same between the KSR and ASR versions so both should show the same behaviour. An ASR will punch a received lower case character as lower case (all bits on the tape are the bits it received) and will send a lower case character from tape as lower case.

I have a couple of Model 33 ASR's here (one Teletype, one Data Dynamics 390, which is the same mechanism) along with the manuals, but neither have been run for some years so I don't want to turn them on without going over the lubrication instructions which will take a bit of time. I can do it if necessary though.
