I don't have one but remember that back in the early 1990s Numrich Arms of West Hurley NY (now Gun Parts Corp.) was selling off Savage parts that they had apparently acquired when one of Savage's plants (Utica?) closed. They had several .22 shot barrels for sale one day when I was in the shop/warehouse, as well as other calibers/guages which I took to be factory prototypes/experiments, including 9mm RF, .22 WRM, .22 Rem Jet, .256 Win., .357 Maximum, and others that I have forgotten. Also odd length shotgun barrels like 32" 16 guage that I suspect were originally intended for export.
I had next to no money and was unable to scoop up these treasures; hope somebody else who cares about these Savages got them. Was only able to buy a very normal used 26" 220 .410 barrel to fit to my ancient 219 .25-20....still have both.
