Hi:
You didn't mention 357, but I have two USFA 357 cylinders that a gunsmith I know bought from Doug Turnbull when USFA stopped making guns.
They are in the white, and have no bushings.
They are not stamped "USFA", but they work fine in my 38 Special Rodeos.
If you are interested, pm me, and we'll talk.
Thanks
