I have a set of 20g. barrels available for purchase.

They are from an H grade.  Serial No. 57786.

They have a concave Matted rib, which is kind of different for such a late gun.

Extractor.  26″ length with Full chokes.  Dolls Head rib extension.

They appear to be Fluid Steel.  They are heavily grayed and patinated.  But I see no trace of twist pattern at all.  So I assume they are Fluid.

They are in overall rough shape with a number of dents and the bores are very pitted and are as thin as .018″ in one area.

I would call these barrels good for parts (rib, extractor), or maybe to sleeve/mono-block.

I will sell them for $125.00 shipped.
