Gerardo, Camilla. Done in Y-arm in 90917

Gerardo and I removed the blank from the X-arm adapter plate A-1C VP5 (T1200220) and swapped the D2000285-v2 type 01 SN 004 nozzle baffle to D2000285-v3 type 07 SN 002 nozzle baffle plate Mitch had prepared, all existing hardware reused and orientation kept the same. Photos before and after attached.  

The fused silica VP for the ITMY IR camera (not currently used for locking of in NLN but we want to keep) was then moved up to this A-1F VP2 location. The camera can itself has not yet been reinstalled, the camera in the can will need to be lowered, a yellow VP cover is there for now. 

We had issues with the CHETA VP ZnSe, so the planned D1700340-type002 VP assembly was not installed in the lower A-1C VP4, a blank was installed instead. A D2000285-v2 type09 SN 003 nozzle baffle plate with a high 2" aperture was installed, this was swapped for a solid D2000285-v2 type01 SN 004 nozzle baffle, see photos before and after.
