Help identifying oil filter

[4x4M38]

I need help identifying the oil filter on my M38.

I've been through the on line manuals as well as Wes' photo pages, and
several vendors pages and can't find one with the ridged top like mine.

The orange would suggest a Fram, and I've seen one with the ridged area on the bottom, but not on the top, and certainly nothing with that weird stamped T-handle on top. Only two fittings, one on the side near the top, and one at center bottom.

Looks similar but not 100% John jr

I have one marked Fram F4P

This site shows a fram description of the F3 & F4. It mentions restrictors needed if oil pressure falls. This may be similar to the restriction orifice in your oil return line.

Thank you Gentlemen.

There are no orifice fittings that I can tell, just adaptors
from the filter canister threads to tubing fittings.

I'm going to watch that EBay auction. Granted it is new,
but if he gets anywhere close to 300 simoleons for that thing
I'm yanking mine, giving it a cleanup and putting it on EBay!

I have seen this type oil filter fitted on jeep engines when used in stationary applications.
With these element type filters, you need to always keep a filter in it--the oil being pushed through the filter creates the restriction needed to keep from bleeding off too much pressure and scoring a bearing.
