Hello,

Succinctly, it is as follows:

1. Mechanical design:

    a. Pull down system to fix the power recycling IM to the EQ stop.
    b. EQ stop for the BS recoil mass.

2. Checked assembly PR/SR drawings. There were few corrections/changes.

3. Checked fastener list. There were few corrections/changes.

4. Checked component list for the manufacture order. There were few corrections/changes.

5. I helped in searching for the PR mirror box missing pieces at Mitaka.

Regards,

Fabian
