hi there
you can check the age of any schneider lens
through the serial number and going to their website:
http://www.schneideroptics.com/info/age_of_lenses/index.htm
i have a schneider super anguolon ( 90mm ) chrome barrel.
it was bought through keh, and was listed as "bargain"
it was not very expensive, and while listed as bargain it was like new
i found it to be a good experience buying through keh, they are a known quanitity,
and actually have a return policy. eBoo sellers often times don't know
(or do they?? ) what they are selling and shrug-their-shoulders sometimes
if there is a problem with items sold. you can also use them (keh) to check prices
for good used equipment. they are one of the largest used camera stores around.
as for differences between the lenses --- as mentioned that angulons do not
really cover a 4x5 sheet, super angulons do with ease ( with movements ).
i haven't used/ seen the fuji you mention, but you might want to widen your net a little bit ...
wollensak made 90mm lenses, both the raptar and a 3 1/2 " exwa
both wollensak lenses are tiny and gave me very good coverage. while i sold them
several years ago, i wish i still had them, they were great.
good luck!
john
ps.
whoops!
should have said "do not cover a 4x5 sheet with lots of room "
