I have been purchasing Atlas Large curves (in excess of and O-72) and like size switches and their Numbered switches for years. It seems that I have always waited and granted my ex-supplier always had what I considered great prices so they probably had an in stock issue due to the pricing. My last large purchase from them I ordered some O-81 curves and like Switches at the end of February. At the end of April I was finally told that they had received an Atlas delivery to complete my order. So to answer your question I think Atlas has always, since sending production overseas, had an issue with stock availability. And I think it is only going to get worse because bringing that production back is made extremely difficult by the Chinese Government. I wish I had a dollar for every time I said "I wish I had gone with Ross and/or Gargraves.".
