Wayne, Chuck, John:
Well, I took Chuck's advice and tried a rubber foot from a stool. It
worked, so off came the front element, which had the haze. After some
gentle cleaning, it's gone - or I rubbed everything off the lens!!!
Longest/most tedious time was getting all the streaks off the lens. It's
back together and I have some film loaded to see what the shutter is doing.
Showing my ignorance here, what I thought were the aperture blades with
perhaps a trace of oil or something on them, were, in fact, the
shutter blades. You do have to look carefully to see the aperture
blades. It's interesting to see that the shutter is in the "middle" of
the lens.
Dug out my father's old Retinette, which is of similar vintage: same
arrangement. One learns something new every day.
Thanks to all for comments and suggestions.
