Yep, the Sew and Vac here just closed in July and I missed it Grrrrrr.
The Alllbrands Organ needles were tested by collectors well versed in testing for alternate needles. The chart can be found on ISMACS. There are Groz-Beckert out there. I previously purchased size 14, but my one source, in US, no longer has any. Another source for packs of 10 is Bob Kovar of Toledo Industrial SM Call 866-362-7397 or 419 380-8540. You may get Organ, Boye or old stock. I have gotten all different ones.
