The new FRAM orange cans are just as good as any other filter. I don't understand the hate for them, as they are clearly a short run filter. That being said, most of them fail after 10k plus runs, when they fail, and on applications with highly questionable service histories, and people complain about it.
As promised...vintage FRAM PH8 cut open

Here is an even better place for it to be
..on my office desk bookshelf at work next to my other bad habit...miniatures of the real thing out in the garage ( but in pieces unfortunatly 
That PH8 looks mighty stubby there...
To OP, No need to waste that 'vintage' PH8. Weld it back closed! The metal is thick enough to take it. Kira

Per the OP's photos, it looks like the filter lays on its side in the box.
DSparks - my Dad had a 1970 Torino GT with a 351 Cleveland. He sold it many years ago to someone who was going to restore it ... it was in good and running condition then.

applied for in 71 by Purolator and gotten in 74 ,so I would venture this was probably a 75 ish era filter for a 62 car or so.but it is probably old ,[censored] I didn't expect to see adbv from so far back ,why the eck didn't I see one before the late 80s start of 90s.was probably more expensive maybe!
ty op for the eye opener!didnt even know Purolator had patented that so far back !hahaha

That patent if for a "combo ADBV/bypass valve". The abstract says:
"A single molded rubber element provides both the relief valve and the anti-drainback valve in an automotive-type oil filter."
So "combo" ADBV/pressure relief (bypass) valve designs have been around a long time, but they don't seem to catch on very well.
The ADBV was invented way before 1971.

Here ya go ... a patent on a filter bypass valve back in June 1930.

dam ,back then ,the patent mentioned a adbv in metal.wow (1956)so patent get given faster then general public use them?i wonder how many patent of unknown stuff there is we don't use !
Wow DSparks - you did it! Thanks for this - I don't think I would have had the nerve to cut it open.
yvon_la: This filter is definitely not newer than 1963 or so since I am sure that Fram kept updating the application list on the box as the years went by and the PH8 was a top seller for sure. That filter fit many Ford engines from the 1957 model year up past the year 2000. As previously mentioned, the address on the filter with a zone# instead of a zip code is a clue too (zips were phased in starting in '63 and required by '67.)
It is interesting to see how the construction of this filter is basically the same or very similar to current filters.

Wow! I had no idea they used fiber endcaps way back then.
Nice! thanks for sharing... looks like double the media area of current ones.
this would have been far more interesting if you had used it
ya they used similar fiber end cap. they ve been using that for a long time ,oh the formulation changed a bit probably but fram prefer fiber end cap ,I tend to agree.im surprised they don't use some form of fiber core instead of metal ,might be they didn't look into it too much !electricity static prevent oil filter maker a lot of things design or material choice wise

The end caps here are also perfectly round. I`ve noticed the end caps on the current Frams are not. They`re sort`ve "octagonal-ish"?

One thing is for sure...the "use NO tools" quote should still be on the filters today, along with DO NOT overtighten! LOL
I think a lot of oil change monkeys still use the oil filter socket or wrench to tighten those filters when installing them!

Only the one on the base end, presumably to promote oil flow.
