I have a 50mm with funges between the first and second element on one copy and funges on the back element of another copy
I got the front group out but it seems to be one solid metal piece with the group crimped or moulded in and impossible to seperate
i have tapped it sucked it, friction drived it but it is STUCK
Any experience or advice please
the other lens back group has a plastic retainer ring that can be reached from the back with grooves for a lens spanner but it only rotates 45 degrees and then locks , this is the more recent one with "made in japan" on the front ring

Many Japanese lens is glued and un-cleanable. Use with fungus it will not impact lens IQ and if you store right it will not growing...

Where can I find informations about that? |
there are 4 editions of this lens and the last 2 with the plastic aperture rings are supposed to be a bit better optically ??? and have made in japan on the front ring
also see Poilu's link
I did a search for "zuiko 50mm disasemble" and got it on a forum but cannot find the site again in my browser history
here is some more info i found
Early Olympus lenses have a letter designation before the word
Zuiko which corresponds to the number of elements in the
lens. Thus, an E.Zuiko has 5 elements, an F.Zuiko 6 elements,
a G.Zuiko 7 elements, and so on. This designation was dropped
sometime in the late 1970's or early 1980's (anyone know exactly
when?) On the other hand, S-Zuiko denotes Olympus' "economy"
line of lenses. Auto-S, Auto-W, and Auto-T stand for standard,
wide, and telephoto lenses respectively, while Auto-Zoom
denotes a zoom lens, and Auto-Macro denotes a macro lens
that must be used with either the bellows or telescoping auto
extension tube.

Thanks Poilu .... got it this time from your link 
Looks like the lens with the funges is the latest edition , the partly plastic one and the front group is pressed in by the factory ( no retaining ring) and cannot be parted
I will use this lens back element to fix the other one with the funges on the back element
