Hi John,a few weeks ago we were discussing the AC air filters, namely the AC A212CWC. You indicated the genuine NOS filters (1967 version) had the diagonally-oriented squares made from soldered round wire with yellow oil-wetted paper. You also mentioned Paragon used to have a 95% correct reproduction. Do you know exactly what the differance was with the Paragon filters as compared to the genuine NOS filters. If you would have a pic of the Paragon filter that would be great. I'm thinking if there is only about a 5% differance they must be very alike. Thanks, Frank
