I need some master help Id-ing my new find. 52' Overlander?

[Ltrain]

Hey team,
I just saw this old Airstream on the side of the road being used as a chicken coup! Full of crap and hay, but in remarkably good condition...with lots of original stuff still in tact. I made an offer and got it! But I can't tell the details on the model. It doesn't seem to be listed on the site, though perhaps I've been misguided in my research. The tag says: "Overlander" and the number is 260552D Also says Jackson Center Ohio. and the Airstream address of "...North Main St, Los Angeles Calif."
It seems that all other Overlanders were 26' though I'd say mine was a bit smaller...perhaps 26' with the tongue though. Hard to tell with all the chickens running around . Is is possibly a 1952? It also says Land Yacht in cursive up above the tag. It has a curbside toilet. And the classic red letters: "1067". It is a double axle with bath in the back.
I can't seem to upload photos right now from my mac. Will try again...

Any interesting history that anyone could guide me towards?
Thanks!

I'm not sure how to read the chart, but it could be a 1959 26' Overlander. Airstream typically includes the tongue in the length measurement, or at least that is the closest. My 25 is supposed to be 25'11" from coupler to rear bumper.

I think 260552D indicates it's an Ohio built Overlander. 552 is the serial number that corresponds with it being built in 1960 and the D indicates a Double Bed. Length is measured from bumper to ball.
