That color was all metal the same as the lube oil filters you notice the top is the same as the.lube oil filters. I believe the plastic cores came with the black Manteca California. Models. To filter lube oil with the black ones remove the plastic and put a washer in the bottom push the paper down against the washer and put on the lid put an orifice at the inlet or use a sandwich adapterThe Australian Jackmaster Classic is working like a champ. No orifice and a Perma Cool universal 189 sandwich adapter. Put a 1/8 inch air tank valve in the lid. With the filter still hot I let air in drains in minutes. In the old days when we used Frantz sandwiches we drilled out the orifice. A pain when the orifice was under the screens.

They were all metal . The white plastic seals came with the black Manteca California models.
Some use the stock white seals. They can last a long time depending on oil temperature.
The origional compressed air filters were all metal the same as the origional lube oil filters.They were all designed to use 2 ply toilet paper. Soft 2 ply was very good at cleaning oil and compressed air. Motor Guards were bad about pinching the 2 ply. Scott 1000 is a lot easier to deal with. I normally use Great Value 1000 from Walmart. With the shorter paper we have now I push the paper down hard against the bottom and put on the top. Remove enough paper to make the paper 4 1/4 inch diameter then it wont pinch in the gasket. Motor Guard tapes the last sheet. I sometimes glue the last sheet. I like the orifice at the inlet. My flat head Ford V8 canister filter is set up for 4 1/2 inch Scott 1000. It has a 5 1/2 inch tall roll of VIVA Signature cloth paper towels in it now.
Those were designed to use 2ply toilet paper. When they were built there was no 1000 sheet or special Motor Guard elements. The same for the lube oil filters. No the full flow filters dont clean oil better now.
They started as all metal. A few used one plastic and one metal core. The black ones made in Manteca California use 2 plastic cores. I just converted a M 30 to filter motor oil. Removed the plastic cores and put a 2 1/2 inch flat washer in the bottom for a core seal. Put a orifice in the inlet. Thats all you need with the shorter 1000 sheet toilet paper. Push the paper down hard against the washer and put on the top. Remove enough paper to make it 4 1/4 inch diameter.
The first ones were all metal the same as the lube oil filters The difference was the early compressed air filters had 1/4 inch pipe ports and no orifice.
The all metal one is the one I would like to find, maybe someday.
Not so sure when they went to plastic cores. Saw one Motor Guard that had one metal core and one plastic core.
Those are compressed air filters from the 60s or 70s. I had one on a DC Case tractor for many years. To filter motor oil you need to install a 1/16 inch orifice. Or better use a Perma Cool universal 189 oil cooler sandwich adapter. I got a few from Jegs years ago.
They were all metal for at least 10 years. The plastic seals came with the Manteca California models M 30 and M 60. Black color. Most of mine are converted M 30s The diesel tractor has a converted M 60 on the diesel fuel. They filter from the bottom up. It has Charmin Ultra Strong in it. The 1000 sheet is too dense to gravity thru.
The Motor Guard M 30s compressed air filters dont need cores. All they need is a flat washer in the bottom larger than the toilet paper core. To be a core seal. I just put a 2 1/2 inch OD washer in the bottom of a M30. I had two 1/8 inch thick by 1 1/4 inch ID. Washers. Had to ream them to put them in. Best if they press on so they wont stick to the used Toilet paper and get lost. They work better with the orifice at the inlet. Also did the Australian Jackmaster Classic. Drilled out the orifice and used a Perma Cool 189 sandwich adapter. There are a lot of Sandwich adapters now. All I have used is the Perma Cool and the Frantz 2 ports from the 60s.
Ralph, don't think they had 2 port sandwich adapters in the 60's, both Perma-cool and Frantz patents are dated 1982-1983, unless you had a time machine and traveled back to the 1960's with an adapter from the 1980's.

I still have some left. Seems like I was using them in the late 60s. Frantz had a bunch of different adapters. They were experimenting a lot with them. Probably before they were patented. I sent 6 Perma Cool sandwich adapters with Gulf Coast juniors to the Bahamas seems like 20 years ago for diesel generators on a private Island. Still have a few Frantz 2 ports left. They are heavy duty.
Yes you are right. I remember doing a Mustang for a guy I worked with. I needed to drain the oil to put in a self tapping hollow bolt. The engine had two drain plugs. If I had a sandwich adapter I would have used it. **** that was 1987.
Hi Ralph,
Thanks for all the good responses here. Earlier in this thread I posted a picture of my Motorguard air filter that has been converted to an oil bypass filter. It is used on my Lister diesel, which has a piston type oil pump, that makes about 5 pounds of pressure, and does not pressure lubricate the bearings. It simply squirts oil on to the roller bearings.
Can you suggest a best TP roll, and would you be willing to share pics of your internal setup?
Thanks!

I need to learn how to send pictures. Ive learned that these filters dont need the center tube like the Frantz. All the M 30s need is a flat washer in the bottom larger than the toilet paper core. I just put a 2 1/2 inch OD by 1 1/4 inch I D flat washer in a couple. Had to ream them a little. 2 1/2 inches is a little bigger than needed but I like the looks of the imprint they make on the used toilet paper. Its best to put the orifice at the inlet. That helps pushing the paper down against the seal at start up. Most of the toilet paper filters didnt use a center tube. The Gulf Coast junior had a center tube but it was only to pull out the used toilet paper. It was about 1 3/8 inch. The Australian Jackmaster Classic has no center tube. Only the seal at the bottom. I use long nosed pliers to remove the toilet paper. I normally use Great Value 1000 from Walmart. Its a little smaller than the Scott 1000. The size of the core doesnt matter as long as its smaller than than the seal. Soft 2ply cleans good but it is bad about pinching in the Motor Guard gasket. The 1000 sheet needs to be 4 1/4 inch diameter. My flat head Ford V8 canister filter is 4 1/2 inch ID. I origionally set it up for 4 1/2 inch Scott 1000. It has half a roll of VIVA Signature cloth paper towels in it now
Some very soft paper might have the core collapse without the center tube. I will get a filter ready for the pictures for when my wife gets home.
