Brian,

     If my memory serves me correctly, there are four standard filter sizes
in the 40 mm range.  They are 43,43.5 (really!),46, and 49.  I assume any-
thing else would be custom or specific to a certain product.  If you want
help with out of date products, try a subscription to Shutterbug Ads.  There
is more old junk for sale in that tabloid than you can shake a stick at.
My opinion is that most of it is junk, but if you know what you're looking
for, there can be a bargain.

     Happy hunting.
