Yeah, I am pretty sure that is the Fram filter.  The book lists four different filters.  The CJ3A parts book illustration shows yours and mine.

My 1950 CJ3A has the filter with no straps and It takes the 4 1/4" gasket.

So, I ordered a oil filter from Kaiser  Willys that was supposed to fit a 3A.  The filter was OK, the right height, but the gasket that came with it was too small, about 4 1/4� and I needed one that was about 4 5/8�.  Seems that up to engine #40352 Willys used a Purolater canister (A-1230) and after that changed to a smaller diameter Purolater or Fram.  It looks like the canister is the same as the Military Junior, with the 4 piece straps spaced close together.  The only marking on the cover is P713.  According to Bob W�s book that would make it about October 1949 for the change.  What do you think Bob?  Here is a photo, yeah it is supposed to be black but I liked the orange ;).
