DEC Tape TU56 head pictures

[Mike Katz via cctalk]

I am in the process or restoring a TU56 so it's in pieces.  Pictures of 
the head were requested so here they are.

These were taken with my phone so the quality is only mediocre.
This, like the rest of the drive, is in the process of being restored.

I'm still not sure how to clean the front of the head where the tape 
touches the head.  Any ideas?

The pics are big so here is a link to the pic:
