Hi all,
Just looking for a guide with step by step instructions and diagrams on how to correctly and precisely disassemble a Aero Ektar 178mm f2.5 lens.

I have found a couple blog posts from photographers who have done this themselves, but it has some key pieces of information or imagery missing which would be very beneficial to have included.

We're there any guides made public when Air Photo Supply Corp sold them to retail and professionals during the War Surplus Specials period after the war?

Many thanks in advance as always.
