You may have a Frantz filter or a similar device that is worth $200 if you want to buy one today
Frantz Filter They filter verry well - in my opinion better than the most other filters.
The toilet paper filters removes particles as small as 1/10th of a micron in size, that is equivalent to the size of particles in cigarette smoke.
I swear by it since my grandpa used it since the 60es on every car he had with good results.
I have one on the 235 since 3 years as a usual bypass and one on the Voyager as an additional baypass to the spinn on filter, but for some strange reason if it comes to oil and filters it is always an almost religious discussion here. :rolleyes:
I cange the toilett paper twice a year - no big deal but you have to refill the amount of oil that the roll contains (about half a quart)
I bought a used one Ebay for $120 and was happy to save some ca$h

So if you wonna get rid of it I´m sure there are some guys that would jump on it.

I don`t want to offend your dad but this is from the original instructions:
"Therein lies the real genius of Mr. John Frantz' patented invention. He designed his Oil Cleaner/Filter to use a filter element that is already widely available and cheap: a roll of Toilet Paper! It has been proven that this roll of thin paper, manufactured and sold for a different familiar purpose, is also a most highly effective oil filter. In the Frantz Oil Cleaner/Filter, the roll is placed over a hollow upright post where it fits snugly. Oil from the engine pressure source flows up through this central post and is forced downward through the circular roll of paper, "from one end of the roll to the other", so to speak, through about four and one-half inches of densely rolled paper. The oil has nowhere to go except through the paper, which is highly effective in trapping fine particles. The bottom edge of the roll rests upon a metal screen which holds it in place. Filtered oil passes through this screen and is returned to the crankcase."
You can put a TP roll in a Fram housing and some guys may have done that, but a real TP filter housing looks way different inside (special carier for the roll, screen, oil flow).
They became popular in the late 50es early 60e and where sold like on a Tupper Party.
My grandpa had - what they called - an EES-Garage back in the 60es and 70es.
Part of AAFES where the GIs over here in Germany had ther private cars maintained and fixed.
I remember that he sold those Frantz Filters a big time back then.
