This tree was probably planted somewhere in the 1950's, as late as 1963 possibly. The previous owner said the tree next to it is a Washington Navel, this one I don't remember what he said, or if he even knew. He's long since passed on so I was hoping someone here could give me an idea of what it might be.

It ripens about 2 weeks before the Navel so in our area, south bay area, northern CA, near San Jose, that's about mid January or so. It is seedless, has a small navel, but not nearly as prominent as the Washington. It is a smaller tree by about 20% (both are standard) and the fruit tends to grow in small cluster. The thing that is the most different from the Washington is the shape of the fruit; it's very oval, not round, and most fruit have a neck. Peel is somewhat thick, easy to peel and has thicker white pith than the navel. Any ideas?

Unfortunately it also has what I think is phytophthora, as it has about 1/4 of the trunk with peeling bark going up and into the branches. However it's had this since at least the mid-1990's or before. Seems to live with it, it always tends to out grow that damage or grow new branches to replace any girdled ones. It is in a lawn, I know, bad, but
has been growing this way for at least 30 years or more. it's at the edge of the grass and I don't think the sprinklers actually hit the bark. They go on either every other day or every 3-4 days, depending on the weather, and usually off in winter.
Fertilized with either Green All citrus food or EB Stone citrus food, about 4 times during the warmer weather, no food in winter.

I tried to post more pics but somehow could only get one per post. OK, I put the rest at the link below, if you're interested;
Any guesses?
