Full set of 3x3 filters in the original box. Also there appear to be 3 extra sets of filters stored in envelopes, dated August 1976. So in total there are four sets here, I can't guarantee they are all 100% complete but they appear to be.
I have no idea if these are useful to anyone but if they are, you can have them free for the cost of shipping, expect something like $10-15 to ship in Canada or to the US.
