That's exactly the A212CW element outer screen we expect to see in NCRS '67 Corvette judging - square mesh, oriented diagonally, of solder-dipped round wire. $2K is a common asking price these days for originals. Photo below.

So since everyone is on the subject, exactly which one would be considered correct for a 67 L78 Camaro form a judging point of view?

I have a question for those who have been around longer than I have. Was the oil-saturated filter paper in these elements yellow when they were new or is the yellowing something that comes with age?

They were slightly yellow when brand new,do to the oil wetted paper and as time wore on they became even yellower, even if never used at all.

Filter paper is impregnated with formaldehyde and other chemicals which is probably what causes the yellowing, although papers manufactured before the last 15 years used a much more caustic/acidic process to bleach the fiber, which causes yellowing and deterioration. (think old newspapers)
I had 200 tons of waste filter paper bales from a DANA/WIX plant, it would give you a headache just being around it for 30 min. It was almost impossible to get rid of, I sent a load to China, they said NO MORE, I ended up selling it to a company that manufactures roofing felt.

I worked on these puppies in dealers back in the mid 60s when they were new, said it somewhere in the Forum before and will again: Initially cars were coming off the truck with the solder-dipped diagonal mesh filters, although occasionally we would see the solder-dipped square mesh, and if ordered from the parts dept a solder-dipped square mesh would arrive; then at some point I cannot precisely remember, everything began to arrive with solder-dipped square mesh. For anyone really interested in getting it right, bottom line from somebody who was there, is that 1965 through 67 either diagonal or square mesh were original and are correct, provided they are solder-dipped. When new, the paper was very slightly yellowed, with age the yellowing darkened.

Here's another distinguishing feature of a production-line 1967 A212CW; the overlap joint of the screen was very uniquely done - reproductions and later service replacements weren't done this way. Photo below is of an original '67 element.

Here's an ac212cw still in the old original box. It's been on a shelf since the 70's from the appearance of the box.

Just curious, has anyone ever seen this type of filter with the print on the inside?

I purchased it a few years ago from a GM dealership out in the boonies, it was hanging up in the attic.

It doesn't have "BEST WAY" or "AC 212CW" imprinted on the ring, however it does have "MADE IN CANADA" stamped in the ring.

Please disregard box as it did not come with one.

Any guess as to what year or even decade it was produced?

Thanks in advance. [img]<<GRAEMLIN_URL>>/youguysrock.gif[/img]
