SBT Rib question

[Curtis Jennings]

Good Morning All: I was on gunbroker yesterday and found an odd SBT. The barrel and fore end appear to be S/N 176759 The receiver and trigger guard are S/N 177086 which is strange in and of its self. But what I don't understand is the rib appears to have rectangular posts not round, is this an early style? I did not find any mention of this style in the TPS.

Haven’t seen one like that.

And it has been restocked too.

Yes, that rib sure is a curiosity. It looks like a milled rib like Ithaca used on their early VR guns.
But there are no photos of the top of it or closer views to try and draw any further conclusions.
The serial number stampings on the barrels and forend look a little suspect as if if they are factory or not. They dont match the frame which we know.

I checked the serialization book and it says 177086 had a 34" barrel and straight stock? This poor SBT has had a hard life.

This poor SBT has had a hard life.

Most of them have.

The square posts are similar to the Moneymaker rib. A look at the top surface would tell the true story. The serial number appears to be an overstamp of the last number. The "1" stamp would suggest an original two barrel set. The greatest feature is the first White Line pad ever made, or at least the oldest survivor.
