Model 62A barrel|Winchester .22 Rim Fire|Forum|Winchester Collector

I have been looking for a barrel for a 62A for some time now with no luck. The one on the gun now, apparently someone in an attempt to clean up the dark spots polished  until it is a smooth bore with a hint of lands. It won’t even shoot minute of barn door now.  Does any one make an after market barrel? or have original barrels for sale. I am saving relining until the last choice.
