Having braved the spiders in the basement to find a metric ruler here's my take:

A - carrier 161mm baseplate 162mm dia.
B 179mm
C 218mm
D 178mm
E 61mm
F 61mm

As for you max width question. I don't see anything that would limit the width.
Carrier used is a LPL 3621-41EX 35mm glassless. Baseplate is from a Saunders/LPL 4550XL.
