Model T Ford Forum: Forum 2016: Help ID Large Rear End. TT? Ruckstel TT? 77" brake rods

Digging through the family stash last week and came across this large rear end. I knew it wasn't mine, so tok some photos.
Not attached to it, but laying next to it were two 77" brake rods, perfectly straight, no angles or bends from clevis pin connector to clevic pin connector, so don't kow if this helps ID the rear end.
My wife thinks maybe a TT Ruckstel rear end?
What is it and what do I do with it?

Thanks in advance.

TT truck rear end, not a Ruckstell.

Approximate year? Or, were they all they same.?
If I list it on the classifieds, I want to give an approximate years of use.

Oop's I looked closer and this is an early version with only 2 spider gears. Was also used on a shorten driveshaft.

Sorry.

I know Hal Davis is in Ga, and maby others with TT's. The brake shoes are a good thing to have spares of.

Fred,
The early TT rear ends did use only 2 spider gears, but how do you know this one has just 2?

Robert,
The thickened bead on the clam shell at the axle tube does indicate it's an early unit. I'm not sure of exactly when that bead was discontinued, but I believe it lasted only the first year or two, so that narrow is down to around 1918-1920 year models.

It's certainly an item you could sell. If you can turn it and determine the gear ratio it would help. The low ratio gears are less valuable than the high ratio gears. The low ratio set will be 7 1/4 and the high ratio set will be 5 1/6:1.

Fred, I don't think that is an early style. While it looks like there is a small bead on the one picture of the housing, it isn't nearly as large as it should be unless it was ground down for some reason.

Justin,
I thought the same thing, but a closer look made me think it was ground down. It's the only explanation I could think of for what I see, although it's mysterious. I can't imagine why anyone would grind it down......
